Comment:
It's not quite that simple. The default implementations are:
{{{
negate x= 0 - x
x - y = x + negate y
}}}
so actually (-) is defined in terms of (+), not negate. For example, if we
have:
{{{
data X = C
deriving Show
instance Num X where
_ + _ = C
}}}
then -3 :: X evaluates to C.
It also wouldn't work for shift:
{{{
x `shift` i | i0 = x `shiftR` (-i)
| i0 = x `shiftL` i
| otherwise = x
x `shiftL` i = x `shift` i
x `shiftR` i = x `shift` (-i)
}}}
I'm not convinced that there are many instances where this would actually
help, so I'm closing the ticket.
