In particular, that "B has CatB?" is a bit surprising, isn't it?
Bill Page replied:
I think you are dealing here with two separate but related issues: 1) *static* typing, and 2) inheritance rules. All types in Aldor are static (or at least *nearly static*) meaning that they must be resolved during the compilation phase.

I'd consider that a bug in comparison of exports. Replacing your (*) line by:
X: CatX == if true then (A@CatX) else (B@CatX);
gives a working program.

So the problem (wild guess) is that the compiler Has problems with seeing that the if statement gives CatX? in both branches of the if statement. Mainly because the types of A and B aro not equal. However, you can hint the compiler. My code is telling him "The if part gives CatX? and the else part gives CatX?". Then the compiler can infer, that the whole "if" statement gives CatX?. And it is at least the type of X (which is CatX?). So it matches.
