Re: Proposal: add new Data.Bits.Bits(bitZero) method

+1 to `zeroBits`. The name fits in with `setBit` etc. I'm also okay with the name `zero`. Twan On 16/02/14 17:45, Edward Kmett wrote:

`bitZero` sounds like it should equal `bit 0`, which it doesn't.

zeroBits ?

You're right, I don't know how I could have missed that :-/

Since the presumed pre-condition for the proposal (that 'bit (-1) == 0' would already hold) I hereby amend the proposal to

(I'm hesitant to consume "zero" from the namespace as was suggested by Henning) _______________________________________________ Libraries mailing list Libraries@haskell.org mailto:Libraries@haskell.org http://www.haskell.org/mailman/listinfo/libraries
