No, probably the correct responce would be a syntax error because I don't think this is legal.

I think it would be a good idea to make it legal and implemented, though, as it would further simplify simple code, if you're only sporking once with no variable parameters then defining it as a function, then calling that seems a bit roundabout.

I'm not aware of any other place where this gets mentioned but the feature requests on the WiKi, perhaps that's what you remembered?
