Hash lookup should be O(1), independent of number of keys. Of course, a hash
with more keys uses more memory, but so does an array with more elements.
But that's a bigger value of 1 from that required for an array lookup.

This is addressed to the participants of this conversation in general:
I think getting to discussions of O(1) or whatever is a bit much for a
language like Perl. It's not designed for speed, though speed is
certainly nice to have. It's also got a fantastic (well, it's got a

Is harder to extend a design goal? You also make it harder to use.

That is in no way different from using strict and having to declare your
