Non sequitur. Warner wrote the "return;" in the same line as the if,
which easily hides it. If the "return;" wasn't there, the original
statement would be almost correct - actually it would be a compile
error, because if (x) int i; is not allowed[1].
Christoph
[1] if (x) { int i; } is allowed, of course.
