[Insight-developers] Postfix versus Prefix operators

[Williams, Norman K]

An interesting discussion, and it just goes to show I can use C++ for 20
years and still be ignorant on some points of the language.

I get bit by it with ITK iterators which are prefix-iterator-only, because
I've been writing

for(i=0; i<limit; i++)
{
}

since 1982.

Maybe as a style matter, we should avoid code that depends on order of
increment altogether?  Aside from argc/argv idioms that go back to the
Kernighan & Ritchie 'White Book', is there ever a good reason to embed
post-increment (or pre-increment) in expressions?
