Comment (by dfeuer):

 I don't think the warning, per se, indicates much. However, there are
 definitely some strange things going on with these types. Lots of type-
 level recursion. I had hoped that the fix for the specializer generating
 loopy code might have done something good here, but as far as I can tell
 this is still an issue in the released 8.2.1.
