What is the minimum version of Python3 being supported

[chwmilcon]

I'm looking at updating the type hinting for Python3 support. I realized that the version of python3 my team is using might be ahead of where antlr wants to support. Has a minimum version been declared? For example, can the:

def func() -> thing | int :

form be used, or should this be restricted to Union[thing,int]

Right now we require 3.6 It seems the pipe syntax requires 3.10 It’s only 2 years old, which means many users won’t have upgraded, notably in large orgs…

Here is the latest version 3.11.5 or an older version 3.8.17.
Unfortunately, the version 3.11.5 is very slow in Java target and extremely slow in Python target.
I'm still working on it.
I will pull it to the antlr/grammars-v4 repository when the speed is right.

I think this thread is about the Python runtime, not the Python grammar ?

Oh, I'm sorry :-)
