Proposal<br>
--------<br>
Remove non-essential abstract methods like __index__, three argument __pow__,<br>
__lshift__, __rlshift__, __rshift__, __rrshift__, __and__, __rand__, __xor__,<br>
__rxor__, __or__, __ror__, and __invert__, numerator, and denominator.<br></blockquote><div><br></div><div>+1 from me.</div><div><br></div><div>I'd support removing all these, minus the exceptions already pointed out</div>
