lark

Some years ago I used the Python library Lark (https://github.com/lark-parser/lark) to parse my programming language. It lets you write your grammar in basically EBNF, builds parse trees (that you can automatically reduce by removing leaves for parentheses, for example) and generates standalone pure-Python LALR(1) parsers for your grammar. Back then, I had a blast with it, it was fast, super easy to use and just worked. Now it's got 5k stars and seems to be a mature and production-ready library. Thus, I vote Python: it has this amazing parser library, it's garbage-collected (no need to fiddle with memory allocations, like in C), it's dynamically typed (so you basically don't need to think about types at all), it now has a `match` statement (!) that makes it super easy to dissect your parse trees and abstract syntax trees.

To add to your survey, I have been reading the lark documentation https://github.com/lark-parser/lark and like the cut of it's jib, I have not used it yet as I don't really have any projects that need a full parser.
