Everyone:
It appears that there is no definitive answer to this issue. FWIW, my opinion
is that polymorphic MOLD arguments should be allowed and that the compiler should use the
dynamic type. The whole purpose of polymorphism is to allow the type of the polymorphic
variable to change dynamically at run time. To use the dynamic type in all situations
except as a MOLD argument would be to create an irregularity in the language.
No matter what the correct answer is or should be, it looks like this is
interpretation material. I may write one up late today or sometime tomorrow.
Sincerely,
