in thread Request help on optimizing a loop for looking up numbers
You can do something like
if (grep exists $hash{$_}, 7..12) {but it's not necessarily any faster.
A hash is an unordered data type, so there's no easy way to search for a range. (There are some "ordered hash" packages on cpan, but that's really a misleading name.)
