Valid point, but Carp::cluck tells you of the invocation point, also. If you would want that globally, you could $SIG{__WARN__} = \&Carp::cluck and comment that out in the final version.

Too expensive for me if there's no other reason to pass named parameters as an anonymous hash: 

use Benchmark qw(cmpthese);

sub f{}

cmpthese (
    -1 => {
        list => sub { f( foo => 1) },
        ref  => sub { f({foo => 1})},
    }
);
__END__
          Rate  ref list
ref   232162/s   -- -88%
list 1989486/s 757%   --

Contructing and destructing a full blown hash only to pass named parameters is just a waste. Breaking named parameters into several lines aligning the fat commata vertically helps. I did commit the gaffe of passing an odd number of arguments as named subroutine parameters maybe twice in all my time as a perl programmer, but more often I've been bitten by missing the curlies for apis which required a hash ref for named parameters.
