Use $# as any other sigil. As you may or may not know, you can use ${...}, @{...}, %{...} etc when dereferecing, but often the curlies are redundant which is why you don't see them so often. In fact, $foo can be written as ${foo} (which is an often seen trick when interpolating $foo in string like "this${foo}that" where $foothat would be interpolated if the brackets weren't there).

Anyway, in your case this means that you'd use $#{$hash{array}} and @{$hash{array}} to get the last element and the array itself, respectively.

See the perlref manpage for more details. Good reading is also to be found in perlreftut, perllol and perldsc
