Yep, but a little better than "toclose", IMO (and the related metamethod 
could be named as "__scope_handler", for example, which is more readable 
and explicit than "__close").

Actually it would be nice if someone could come up with a word that coul 
express the real concept clearly. For example: "at_scope_end" (or and 
"__at_scope_end" as a metamethod. Of course those are UGLY.

Maybe "atend"? It's more explicit than "toclose" since actually 
describes that something happens when execution flow reaches the "end" 
keyword. "__atend" is not bad as a metamethod.

Mmmh, here the syntax is getting really messy.
