GNU Parallel, where have you been all my life?
I use Go. You can run scripts with go run directly, and this package makes shell tasks easy: https://github.com/bitfield/script

Scripting with Go: A Modest Proposal
If you're not deeply familiar with Go there is one detail missing from this post (though it's in the script README) - what a complete program looks like. Here's the example from https://github.com/bitfield/script#a-realistic-use-case
package main
- 'script' is for writing shell-like pipelines in Go

Is there anything golang similar to python plumbum?
I would say bitfield/script is the closest thing to plumbum. You should check out this article written by the author.

Change go code behaviour at runtime
There are lua and Go-script options. My impression is that a few are well accepted but perhaps just a little less widely used than the first two. I cannot speak from personal experience on them. Shopify has a Lua 5.2 port: https://github.com/Shopify/go-lua and I know https://github.com/bitfield/script is one of the Go-like scripting languages, but I think it's more for a shell script replacement than embedding.

Planning to learn Go, does it have this feature?
Parallel to my other comment, u/Akirapearl, if you find yourself getting annoyed at Go’s system-language focus, you might find John’s “script” Go library useful: https://github.com/bitfield/script

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.
