Enumerable.Iterate counts the items it's seen using a simple int. There exists
a minute chance to iterate over a sequence with 4^n, n >= 16 elements. As any
such sequence would evaluate to (int)0, the iteration would throw. As this case
is extremely unlikely, this behaviour doesn't hurt anyone - but since the
counter is only compared to 0, a simple bool flag would do, with less possible
side effects.
