I have a base class A, where I make specific operator depending

this:
c is a class derived from A
bool shouldDoX = (cast(X)c) !is null || (cast(Y)c) !is null ||
(cast(K)c) !is null ... ;
as the number of cast(C) !is null is growing, I'm afraid of
this being a inelegant or even poor performance approach. How
would you do that?
I would just use an (empty) interface on that classes and do test
for that.
