I was guessing.  I see that the check is for var->type, whereas perhaps
val_print prints out children if var->val->type is a struct/class.  But I don't
know the relationship between the two and you're the expert in these matters.

I don't really know much about that end of things yet.  I've looked mainly
at the mi directory and variable objects.
