Uh, I dunno.  Like Python/Ruby, but without the consistency.

I think special constructs -- defined as NOT doing assignment
-- should be allowed to set up aliases.  This includes, e.g. for().
Perhaps a simple

        alias( %foo, %bar );

for those times when you really just need a simple WTDI!

Multiple aliases in one swoop:

        alias
                %foo => %bar,
                @p => @Some::Other::Long::Class::Name::ISA,
                $x => $db{tbl}{col}[r],
                $y => substr( $s, 10, 15 ),
                @z => @a[5..8,13];

etc.
