Bitwise

[rlopzc]

Hello, is planned that core/Bitwise works with Bytes instead of Int? Or support both?

[evancz]

There is no plan to have bitwise operations on arbitrary Bytes values, so I will close the issue on those grounds.

That said, I am curious what you are trying to do. Do you need bitwise AND on two arbitrarily sized Bytes values? If so, why?

I was just curious because some cryptographic packages simulates the bytes working with a List Int. Now that we have core support for bytes, they may work with them directly instead of List Int. If that's the case, when doing cryptographic stuff the would use bitwise operations like AND, or XOR directly to the bytes instead of decoding it to a List Int
