So `ord` is already a really fast function with (last check before this thread
was posted) 166 nsec per loop. But I'm wondering... doing `ord(a)` produces
this bytecode:
> 2 4 LOAD_NAME 1 (ord)
> 6 LOAD_NAME 0 (a)
> 8 CALL_FUNCTION 1
> 10 POP_TOP
> 12 LOAD_CONST 1 (None)
> 14 RETURN_VALUE
But doing `+a` only produces this:
> 2 4 LOAD_NAME 0 (a)
> 6 UNARY_POSITIVE
> 8 POP_TOP
> 10 LOAD_CONST 1 (None)
> 12 RETURN_VALUE
So an operator has its own bytecode, doesn't need to `LOAD_*` a function, and
doesn't have the impact on performance when converting arguments to the format
of the (after `POP()`ing every argument) TOS function and then calling that
function. And also, the unary `+` of strings only copies strings, which should
be redundant in most cases. Maybe `ord` can take the place of unary `+` in
strings?
