The \loop macro defines \body to be the contents of the loop.  Nested
loops must be at a different level of nesting so the outer \body is not
overwritten by the inner.  So put \begingroup before the inner \loop
and \endgroup after the inner \repeat.

Stupid construct: sad but true.  \iterate has \else in its definition so you 
can't write \ifnum\x>\xlimit\else.
