Is there any way that we can avoid even getting the idea that this is an
sfk_constructor?  Your patch seems like it's a bit later than we'd like;
we're concluding that the function is sfk_constructor and then backing
out when we notice that ctype is NULL.  Can we just avoid concluding
this is a constructor at all?

Thanks,
