Sure, I know about the underlying implementation. I was just hopeful
because several of the array functions handle the maps differently
depending on whether the keys are numeric or string or both.

If I wanted to get cute, I could store the value in the key (e.g.,
array('value 1' => 0, 'value 2' => 0, ...)), and that allows me to use
the '+' operator. In spite of the nice performance benefits of this
approach (leveraging the hashes benefits), the code that utilizes the
arrays becomes quite clunky.

Thanks,

Adam
