The number of times i *sigh*ed at having to reinvent deep operators in a clunky way in Perl 5 is really not in line with Perlishness and DWIM. Also ~~ is deep in exactly the same way. Perl is also not low level. I could build it, and I have, but I don't want to. It can short circuit and be faster when the structure is definitely not the same (totally different early on) or definitely the same (refaddr is equal, etc).
