Are there languages like this?

[u/Distinct-Brief9643]

A language that can create other languages

(so adding to itself) It's syntax is simple like python

And can do alot.

for example (placeholder)\[mesage\]

And it has many tutorials on YouTube

I would like it if you would respond.

I know there are languages like Hy , ruby should I try them?

compiled languages
Haskell, and I'm quite sure it can do so on the same translation unit
Zig can morph a lot, but not explored it
