Thanks the reply,
Could you clarify slightly what you mean by the Python's normal
restrictions. I was guessing the restriction might be something like:
"When compiling a list of types, if the list contains a class B which
inherits from A then A must be contained in the list."
The interesting thing here is that the call to CompileSubclassTypes
works when we pass it one huge list of types, but not when we call if
repeatedly with smaller lists.
