Support Python 3.12 Syntax for Generics (PEP 695)
Support for the new type parameter syntax introduced in Python 3.12 is now enabled by default,
documented, and no longer experimental. It was available through a feature flag in
mypy 1.11 as an experimental feature.
This example demonstrates the new syntax:
# Generic function
def f[T](https://github.com/python/mypy/blob/master/x: T) -> T: ...
reveal_type(f(1)) # Revealed type is 'int'
Generic class
class C[T]:
def init(self, x: T) -> None:
self.x = x
c = C('a')
reveal_type(c.x) # Revealed type is 'str'
