Hi, The Python Steering Council accepts PEP 585 "Type Hinting Generics In Standard Collections": https://www.python.org/dev/peps/pep-0585/ Congrats Łukasz Langa for your tenacity! (PEP written one year ago.) Thanks also to everyone who was involved in the discussion to help to get a better PEP ;-) It seems Guido van Rossum is already working on implementing the PEP: * https://github.com/python/cpython/pull/18239 * https://bugs.python.org/issue39481 Victor -- Night gathers, and now my watch begins. It shall not end until my death.
