To do this EVERY object that you might list as alternatives would have to support `__or__()` and `__ror__()`.
Moreover, for many types, `|` is defined with conflicting meaning. E.g. `3 | 5 | 11 == 15`. But of course 3, 5, 11 aren't the unique collection of numbers that bitwise or to 15. At runtime, we'd have no idea what the alternatives so expressed were.
