In STL implementations that I'm familiar with (GCC, CodeWarrior), std::copy is
not simply a while loop. Its implementation is in fact heavily overloaded:
- memmove for built-in and POD types (using compiler-specific ways to detect
PODs);
- specialized algorithms for copying data in known containers (e.g., chunked
copy for deques in MSL);
- a for loop for random access iterators in GCC (helps the optimizer);
- a while loop otherwise.

To duplicate the behavior for PODs, we'd need to introduce quite a bit of
compiler-specific code.
