Well, if D has an "open" (I like that better than "custom", cannot one
choose to use an interface that just happens to be the same as used in
C?  Perhaps this is semantic or perhaps the issue is real -- I can't
really tell.

I think D and C are disjoint by definition: C uses a "uniform" set of
operations  and D uses custom-defined operations.  (BTW, I think I agree
with Walden's point that "custom" a better antonym for "uniform" than

The alligator wrestling was about whether F overlapped C as well as D.

BTW, what is the set theory term for two sets that have a non-null
intersection but neither is a subset of the other? "Overlap" sounds good
because they visually overlap in a Venn diagram, but that may not be
