Let's make one thing clear; while decorators may be useful for some to experiment with attaching signatures to methods, mainstream Python will eventually have optional static typing built in, and it won't use decorator syntax. (More likely you would specify argument types by saying e.g. "def bar(low: int, high: int) -> float: ...")

that could, of course, be seen as rather strong argument against having decorators after the def but before the colon; let's reserve that space for information about the return type (or types).

(more about decorators later)
