Issue 33107: Feature request: more typing.SupportsXXX (original) (raw)

Currently in module typing we have the following classes

• SupportsInt
• SupportsFloat
• SupportsComplex
• SupportsBytes
• SupportsRound

There is no reason that people only need these classes. They may need, say, SupportsIndex to denote all integer like types, SupportsAdd for arithmetic types, etc. It is best that the list of SupportsXXX are expanded to be as complete as possible, and even better, a mechanism for user specified SupportsXXX be provided.
