A&&B is not so terrible, since you can do it by nesting, as above.
The big problem is A || B. It creates a mess.
version(A) version = AorB;
version(B) version = AorB;
version(AorB) {

Yes. And that sucks, because you've got the version statement in two
places. And you've had to create an essentially meaningless temporary.
[1] Then when you have a more complex expression, especially where A and
B appear more than once, it gets disgusting.
[1] I know Walter's idea is that you create meaningful identifiers, but
in practice this kind of versioning can be a workaround. EG B is
"everything except WindowsME".
