I have some doubts. See perlfunc -f keys, from which I quote:
If you say
keys %hash = 200;
then `%hash' will have at least 200 buckets allocated for
it--256 of them, in fact, since it rounds up to the next power
of two.
So, in summary: with this new syntax, you cannot safely distinguish
keys %hash = 200;
from
$hash{200} = undef;
