I'd say this is not often encoutered.
One should avoid using a different type then size_t for the index, as it can have negative performance implications.

Interesting. What would be the example of negative performance implication? I'm guilty of using the int on occasions.

on 64bit a downcast can cause the compiler to emit a cqo instruction when the index is used as an index. it's relatively expensive in some circumstances when it messed up predictions.
