Right. I haven't thought about it. My off the cuff response is that we
should disallow it if the amount of effort required to detect it is
within reason. Alternatively, we could simply impose a global limit on
the depth of the recursion. Either appears reasonable to me, but I may
be overlooking something here...

Thoughts?
