Original I had it as a class. I'm not sure if it matters much 
between a class and a struct though?

In any case, I solved this problem by using an attribute to test 
instead of using isMutable. Obviously this requires adding a 
symbol but not a huge deal.

e.g.,

@Enum immutable struct ...

and hasAttribute(T, Enum) replaces isMutable(T).
