With `q.hs`:
{{{
module Foo where
foo :: Int
foo = ceiling 6.3
}}}
I get:
{{{
$ ghc -fforce-recomp -c q.hs -Wall
q.hs:5:6:
Warning: Defaulting the following constraint(s) to type `Double'
`RealFrac t' arising from a use of `ceiling' at q.hs:5:6-16
In the expression: ceiling 6.3
In the definition of `foo': foo = ceiling 6.3
$ ghc -fforce-recomp -c q.hs -Wall -Werror
$
}}}
