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.
