Proposal: add new Data.Bits.Bits(bitZero) method (was: Proposal: Explicitly require "Data.Bits.bit (-1) == 0" property)

I'll have to come down against that proposal because, at least on amd64 for 64 bits-sized types (Int, Int64, Word & Word64), it doesn't works.

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

Introduce a new class method

class Bits a where ... -- | Value with all bits cleared bitZero :: a ...

modulo naming of 'bitZero'

(I'm hesitant to consume "zero" from the namespace as was suggested by Henning)
