Without any thought at all to whether this would be implementable in Python < 3.x, using Python 3 annotation syntax as a guide. (I say this not knowing if the new annotation syntax is an all or nothing - i.e. both parameters and return values - approach or not.) Python 3: > def f(x:int, y:list) -> float: Would this make some sense, and is it implementable: def f(annotated, parameters, or not) -> xml: def f(annotated, parameters, or not) -> string: Having just written that, it is perhaps not such a good idea as it may perpetuate the notion that only the return value is "xml" or "string". As for your proposal: > def f:xml(): > def f:str(): I like this better than ``@[xml]`` if for no other reason than it is easier to type. I also think it looks cleaner than the decorator-like syntax.
