Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Asking for advice to get deeper understanding of golang internals.
I started doing this a few years ago when I wanted to add programmability to another system I was working on, and didn't want Lua or anything else like that. I set it aside when other priorities arose, and didn't return to it when I saw that others had already done the same thing (yaegi, tengo).

Go: What We Got Right, What We Got Wrong
Yes. There are long standing feature requests for (e.g.) the reflect package that simply don't get done because they'd break this assumption and/or force further indirection in hot paths to support "no code generation at runtime, ever".
Packages like Yaegi (that offers an interpreted Go REPL) have "know limitations, won't be addressed" also because of these assumptions.

Can Go run statements in cmd like Python?
I think https://github.com/traefik/yaegi comes as close as using the python interpreter in you CLI, but for Go

Can Go files be compiled by themselves?
There's a go interpreter: https://github.com/traefik/yaegi It could run programs without compiling them, but there're some limitations.

referencing packages on the internet and using go plugin
I'd recommend looking into a different approach for plugins such as hashicorp/go-plugin (which uses multiple process PIDs and RPC communication between them) or traefik/yaegi (which implements a Go-compatible scripting language that can be interpreted at runtime and which still supports most Go modules).

Mun v0.4.0: a statically-typed scripting language like Rust, written in Rust
Why do we need a language like Rust when we have Rust. Why not just create a Rust interpreter. (There's such an interpreter for Go, BTW, https://github.com/traefik/yaegi )

Plugo - A plugin library for Go.
A cool solution I saw was Traefik's yaegi module. They basically created an interpreted scripting language with Go compatible syntax (turning Go into an interpreted, not compiled, language). I haven't tried this but it sounds like it brings the better parts of dynamic languages like Python's plugin support to Go - plugin writers can still write "Go" code, which can load dynamically.
