Unravelling Python source code.

Unravelled syntax

1. obj.attr ➠ builtins.getattr(obj, "attr") (including object.__getattribute__())
2. a + b ➠ operator.add(a, b)
3. a - b ➠ operator.sub(a, b)
4. a * b ➠ operator.mul(a, b)
5. a @ b ➠ operator.matmul(a, b)
6. a / b ➠ operator.truediv(a, b)
7. a // b ➠ operator.floordiv(a, b)
8. a % b ➠ operator.mod(a, b)
9. a ** b ➠ operator.pow(a, b)
10. a << b ➠ operator.lshift(a, b)
11. a >> b ➠ operator.rshift(a, b)
12. a & b ➠ operator.and_(a, b)
13. a ^ b ➠ operator.xor(a, b)
14. a | b ➠ operator.or_(a, b)
