hmm good point...

you are forcing everything into an array,

maybe

sub size { scalar @_ }
is easier to read.

it's like explicitly wrapping lists and arrays into scalar @{[ ... ]}

But w/o prototypes this would mean to copy huge arrays around...

And something like size %hash couldn't be extended to find scalar keys %hash.

Anyway your example fits as a proof of concept! =)

(But an efficient implementation should be done in XS. Edit: see benchmark)

Cheers Rolf
