Comment(by igloo):
Replying to [comment:17 ross]:
> It could be done by having abs minBound throw an exception (which seems
justifiable).
That sounds sensible, and would handle the result of
{{{
minBound `gcd` minBound :: Int
}}}
correctly, but we wouldn't want to get an exception from taking `abs` of
the arguments in
{{{
minBound `gcd` (minBound `div` 2) :: Int
}}}
