I don't see the problem. You have to access the thingy's 'data' through 
the 'burble' member, so there is no ambiguity, is there?

This would be different, and dmd rejects it accordingly:
----
union flob {
	ulong data;
	struct {
		uint data; /* test.d(4): Error: variable test.flob.data conflicts with 
variable test.flob.data at test.d(2) */
		uint bits;
	}
}
