in thread Why doesn't Perl provide %_ as the hash equivalent of @_ in subs?

sub withNames{ local %_ = @_; ++$_{$_} for keys %_; };;

Try  ++$_ for values %_;

:P lol

Yeah, local %_=@_; is not hard to type :)

    Try ++$_ for values %_;

    That improves things:

    sub sansNames{ ++$_ for @_; };; sub withNames{ local %_ = @_; ++$_ for values %_; };; cmpthese -1,{ a=>q[ withNames( 1 .. $_*2 ) for 1..5 ], b=>q[ sansNames( 1..$_ ) for 1 .. 5 ] };; Rate a b a 35072/s -- -71% b 122333/s 249% --

    Though ... a benchmark of named parameters that doesn't use the names to access the parameters ... :)
