Thread: Iterator quandary

I see that with the precedence thing we were talking past each other for the most part. You are absolutely correct that the pointer version behaves as if the dereference happens first since it happens to the pre-incremented object. So if you were to expand x = *p++ you would rewrite it as x = *p; ++p, dereferencing the pointer first.

Well it is bound to happen sometimes. Thanks for the input, by the way. It really did help push me towards a more satisfactory solution. The "iterant functor" paradigm is very simple, which is great from the standpoint of someone working on an third-party library, as it should be much easier for users to conform to such an interface. No confusing C++ incantations, just define a few simple member functions and done!
