Note that this is legal, standards conforming code. It doesn't use
pointers, casts, unions, mutables, and it's single threaded. There's no
attempt to subvert the type system. It's even const-correct.

But 'end', despite being 'const', has its value change during the loop.
It isn't loop invariant.

So what has const as type modifier, as well as const-correctness,
brought to the table to justify all the effort and hype spent on it?
There's got to be a better way.
