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

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 ... :)

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
