Hello,

Thanks for your PR. Can you elaborate on your design? Why create a BitwiseAnd class, in particular?

Thanks for your PR. Can you elaborate on your design? Why create a BitwiseAnd class, in particular?

I was trying to mimic linear-base approach on tackling Num class i.e. a class per method. Data.Bits class is pretty populated with methods too. I haven't defined Bits in PR just because not sure about getting review responses so saved on initial efforts ;).

I don't have strong opinion about particular class name and open to alternatives.
