At least an inconsistency. Since the docs don't say what a repeat operator
with more (or less?) than one argument is supposed to mean...

Personally, I'd disallow repeat operators with argument counts different
from one.

Usually, I'm for extending interfaces as far as it gets, but in this case
there doesn't seem to be an obvious and compelling extension (sequence?
alternative?), so I'd feel that there is a footgun for little gain.
