Oh, hm, this uncovers an inconsistency in how we format constructors, depending on whether they are decorated or not. IMO def [T] list(self) -> list[T]looks better than def [T] __init__(self) -> list[T]I will see how many tests needs updating to converge on this option, and if not too many, I am going to do it in this PR. |

Yeah, no, 15 tests need to be updated, this will also probably cause some noisy |

This is mypyc-specific optimization:
dictcreation is quite slow, so we should not create a dict in theCallableTypeconstructor. Instead, I store the required info on the relevantFuncDefobject (and restore the link to definition infixup.py). Quite surprisingly, this gives 2% speedup on my desktop.
