Beter:

enum E = 1;
struct Foo{
	enum X1 = E;
	static if(1) enum E = 2;
	enum X2 = E;
}

static assert(Foo.X1 != Foo.X2);


class Bar{
	enum X1 = __traits(isAbstractClass, typeof(this));
	static if(1) abstract void bar();
	enum X2 = __traits(isAbstractClass, typeof(this));
}

static assert(Bar.X1 != Bar.X2);


mixins has same problem.
