[Development] qsizetype and classes working with QStrings or QList

[Scott Bloom]

Or

for( auto ii = 0; ii < std::vector.size(); ++ii )
{
}

since there is no suffix for "size_t" and the size of size_t will depend on 64 vs 32 bits whats the best way to AAA the index iterator?

AAA is a non-solution from the ivory tower.

It's a pain for human reviewers and tools operating on less then a full translation unit.

(Almost) real-world example:

    for (auto i = foo.guess_stuff(); --i >= 0; )
      do_something(i);

Good? Bad?
