Vyper or something else about fe

For some context, converging on the language syntax will probably mean that they have to write their own parser instead of depending on the python stdlib parser. IMHO, reliance on the stdlib parser was one of the things holding the language back and even encouraging patterns of corner-cutting that led to bad engineering practices. It would be great if the python vyper was willing to write a custom parser, but it might be a big ask.

Edit: I am working on an update to streamline the grammar a lot vyperlang/vyper#1827

The eventual idea is that if it's good enough to pass test suite, it should be good enough to start on a refactor of the compiler front end. I would eventually like to move to Lark fully: https://github.com/fubuloubu/vyper-redux/blob/master/vyper/ast.py#L229 details an idea of how this might look
