Return type for Decorate weapon functions

[Rip and Tear]

Suggestion:
Add return types to Decorate weapon functions like A_CustomPunch for accessing the actor hit by the attack (if any).

I don't think that's possible for the simple reason that multiple actors can be damaged in one hit, and ZScript has no method of handling multiple return values like Lua (as far as I know).

Plus, certain "hits" have a delayed effect and therefore can't be returned by a function like this anyway.

It wouldn't be feasible for every single attack function, but there are still functions like A_CustomPunch and A_Saw that preform instant hitscan attacks that can only hit one target.

[wiki=ZScript_functions#Multiple_Returns]The wiki says it can return multiple values, apparently.[/wiki]
Couldn't it return a dynamic array anyway? (Since IIRC ZScript has those natively)

Multiple returns in the given context are not possible because you need to know up front how many values there are, and there's an internal compiler limit of 8.
Dynamic scripts cannot be returned because those are not but structs internally.
