In the above case yes but as the number of keys is increased the buckets will get reused and the result won't be correct:
$ perl -le '%h = (1 .. 10); print scalar %h' 5/8 $ perl -le '%h = (1 .. 12); print scalar %h' 5/8 $ perl -le '%h = (1 .. 100); print scalar %h' 33/64

Actually, I searched for a genuine use for this feature for a long time and I almost found one: Power Twool.

    Oops. I completely misread your original post. I thought it was elements/buckets, not used/total. That said, given Perl's non-object data model, the only other way to provide this info would be through yet another function.
