Where would the line be drawn? Would using map in "void context" spew its return value into @_ ?

DWIMery shouldn't venture into the "Do What I Wish" if doing so creates serious language inconsistancies, IMHO.

My memory may be incomplete or in need of refreshing, but I can't think of any subs that populate $_ as a default lvalue. Yes, there is the diamond operator in the special case of a while() loop, there is foreach(), the m// and s/// operators, and there are subs that utilize $_ as a default parameter. But there aren't any subs I can think of that populate $_ as though it were an lvalue.
