__rlshift__, __ror__ in Python

Question

I noticed that this recipe apparently uses __rlshift__ , __ror__ as operators. But they are not in the documentation ! Can someone explain this and maybe point to some documents?

Answer 1

See the documentation for:

• object.__rlshift__()
• object.__ror__()

__rlshift__ is the version of the replaced __lshift__ operands used when the right operand supports the operation, but the left operand does not.
