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

It would be silly to always create a hash from the arguments.

So either create it yourself (local %_ = @_; or alias local %_ = @_;) when it's acceptable, or create an attribute you can specify on a sub which does it for you (e.g. sub foo :named_args { ... }).
