how to make a context aware code evaluater like REPL
hi! I was looking at REPL-like evaluation of code from here and here, and tried to make a very small version for it, yet it fails:

DI as a first class citizen?
Second, any "inheritance" is optional. Quoting nqp's 6model overview with my added emphasis:
-
What's the position/name of Raku(formerly Perl6)'s `grammar` in parsing technology?
Considering it has a compiler (which generates an NFA), I do not think it is fair to call it an interpreter.
-
What would Raku look like without any syntactic sugar?
When I mention the Actor model, I specifically mean the Actor model, not "an actor model". That is to say, a mathematical theory, not an implementation. In contrast, ponder what you mean by "an object model". When I mention the "metamodel", I specifically mean "a framework [that] does not contain an implementation of classes, interfaces, roles, prototype objects and so forth".

Raku: features, community and main interpreter/VM
NQP is a compiler like MiniPerl for Perl 5. It is a bootstrapping tool which helps to compile the Raku parts of Rakudo and compile the libraries before running have compiled the libraries. Unlike MiniPerl for Perl 5 (which is an interpreter that can interpret all Perl syntax but miss some batteries: means without modules mixing Perl code and native code), NQP can only compile a "simplified Raku". NQP refers to both the compiler and the source code contained in files with the ".nqp" extension.

When implementing a language, what's your favourite backend?
I focus on the Raku stack: the compiler Rakudo which targets the compiler compiler NQP which targets multiple backends including MoarVM. (Which

Common standard library for language interop
NQP is a compiler compiler toolkit that targets multiple backends: JVM, JS, and MoarVM.

What Happened to Perl 7?
> Perl 6 was treated as the successor of Perl 5 -- and that was the mistake. It meant Perl 5 started dying,
Perl 6 took a long time to make, but how much did that matter? What was Perl going to do about Rails, Clojure, Go, Rust, JS/TS, and more? The world of programming languages used to be a lot smaller than it is today.
> Perl 6 had a new different syntax.
Inline::Perl5 [3] allows running legacy Perl 5 code in Perl 6 codebases.

OpenBSD for webserver?
Perl can be faster and defiantly nicer to work with than PHP but it's nowhere near as fast as some other options like Rust but that has the downside of being much harder to write and get working. Perl has the advantage of being prepackaged with the base system and on OpenBSD it's kept up fairly well with the system version currently being only one version behind the latest yearly Perl release. There are some patches added to the OpenBSD version so updating it each year takes time. The easiest way that I've found for running Perl websites is to leave the system modules as is and to install all of the modules that you need into a users home directory with local::lib and cpanm. That way the system install isn't contaminated with the extra modules and it makes deploying easy because it's all contained in one users home directory that can be rsync'd or tar'd. Another nice thing is you get access to pledge and unveil through Perl so you can lock down your website even further. I've recently been trying out doing things in Raku (Perl6 was renamed to Raku in 2019). It's slower than Perl most of the time but I find Raku to be so much more beautiful and expressive that it's a joy to code with. There aren't as many modules available right now for Raku but it gives you access to all of CPAN through the Inline::Perl5 module.
- Is there any interest in a Raku implementation of Mojolicious ?

Interfacing with Perl 5 with Inline::Perl5:

The Future of Perl
I'll be happy to dialog about this compatibility, but the key thing is to start with an open mind; a recognition that the original vision predated Parrot; and a recognition that Rakoons have never relinquished that original vision even while many of us are delighted that Perl folk are keeping Perl healthy as a separate thing in its own right.
To be clear, the realization of Larry's original vision is not constrained to interop with Perl. Raku has extraordinary potential, some already realized, for pan-language compatibility via its [Inlines](https://modules.raku.org/search/?q=inline).
The steady improvement of [the exemplar Inline](https://github.com/niner/Inline-Perl5) for the last 6 years; its evident maturing; its suitability as a solid blueprint for upgrading all the others; all of this bodes well for being able to use a lot of the world's best existing code from within Raku this decade, with Inline::Python quite plausibly shining in this regard within the next 2-3 years.

How C++ supports the whole C's library and how I could do the same if I created a language?
The most polished of the Inlines, namely Inline::Perl5 (github repo) enables devs to instantiate Raku objects that are instances of Raku classes that are sub-classes of Perl classes. It does this even though Perl has pluggable OO, essentially arbitrary OO, with dozens of different OO systems available, all of which differ from Raku's, for example having a variety of MRO linearizations that aren't C3. So such things can be done.
What are some alternatives?
