Perl support in Liquidprompt
So here it is, a PR with a new implementation of Perlbrew support to the latest version of Liquidprompt and as a bonus, I also added support for plenv and alternative to Perlbrew for handling your Perl installations.

Script to install existing modules into new perlbrew env/perl version
If you don’t care that the version isn’t exactly the same 100% of the time, you can use do sh perlbrew clone-modules (that’s plenv migrate-modules for plenv users). If you want real dependency pinning per project you’re better off using something like Carmel on top of perlbrew or plenv so you can specify what versions of each module you want in your cpanfile, run carmel install whenever you switch to another perl version, and then it should just be a matter of letting Carmel find/load the right versions of each module for you with carmel exec …

Installing perl with perlbrew
Since perlbrew has wholly met my needs, I have not spent much time with plenv. This is not a critique, just my point of view. One warning contained in the plenv read me is:
- What Happened to Perl 7?
- plenv - Installation of Perl on user directories 2022

Nice article. You mention preferring plenv but you only give it passing mention. It would be nice if the article also explained the installation process for that.

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.

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.
