That's nicely exemplified by the fact that the code above does a
redundant increment (or did a redundant increment would it work, the {}
are missing) solely to work around the fact that the "for loop
mechanics" of checking the condition before the loop body is executed
and performing a "variable increment step" afterwards are ill-suited to
this particular problem ...
