2. "x || y" because Cython's "x or y" generates complicated code which isn't
optimized as well as "x || y".
I just tried using gcc -O3 and the resulting assembly is identical.
Well, that would depend on what x and y are.
A very concrete example:
"if isinstance(x, (int,long))", which is parsed as "if PyInt_Check(x) or
PyLong_Check(x)" is slightly slower than "if PyInt_Check(x) ||
PyLong_Check(x)".
