I once had an app which needed to generate long continuous ranges of
alpha codes. But even then I did not implement -- in PHP userland.

I think if there is a need for --, each application would need its own
"correct" behaviour. AAA-- may be AA or ZZ or ZZZ or ZZ0 or ZZ9 or even
0ZZ depending on use case.

If there is a reason to do this in C rather than PHP userland code, it's
probably best fit in an extension.
