However, `complement` is not well-defined for `Natural` and this consequently renders the default implementation of `clearBit` dysfunctional. This implements `clearBit` in terms of `testBit` and `setBit` which are both well-defined for `Natural`s. This addresses #13203 }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/13203#comment:7> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
