[Python-Dev] Re: RFC on Callable Syntax PEP

My proposal wasn't to make the body optional based on the presence of a decorator, but rather to return a "function prototype" iff the body does not exist (I probably should have made my made my own reply instead of piggybacking on his proposal). I also mentioned some form of expression to represent this, similar to lambda. Maybe a friendly error message telling the user to use a function when this thing is called would alleviate some confusion? I'm not sure how one would forget to add the function body anyway.
