--- Comment #8 from hsteoh at quickfur.ath.cx ---
I'm surprised this worked in older releases. Or *appears* to work -- it's
probably actually broken because cycle() returns an infinite range, but when
the input is empty, it can't be an infinite range. So this is one of those
places where the compile-time requirement of isInfinite breaks down.
