The obvious solution is to refactor Bar, but in the real world, it is much harder and life would be much easier if I could remove foo from exists inside S. At worse, if Bar did depend on foo, I would simply get errors about missing foo.

I doubt it is possible, but maybe some tricks?

you could define a flag for foo, like:

mixin template BAR(bool addFoo = true)
{
    mixin FOO;

    static if(addFoo)
    {
        void foo(){}
    }
}
