Comment:
With this module:
{{{
type F a = Char
type G a = Bool
f :: F Float Double
f = 'c'
g :: G Float Double
g = True
}}}
I can reproduce this with 6.8.2:
{{{
GHCi, version 6.8.2: http://www.haskell.org/ghc/ :? for help
Loading package base ... linking ... done.
[1 of 1] Compiling Main ( f.hs, interpreted )
f.hs:9:5:
Kind error: `G' is applied to too many type arguments
In the type `G Float Double'
In the type signature for `g':
g :: G Float Double
Failed, modules loaded: none.
Prelude>
}}}
but not the HEAD or 6.10, e.g.:
{{{
GHCi, version 6.10.1: http://www.haskell.org/ghc/ :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer ... linking ... done.
Loading package base ... linking ... done.
[1 of 1] Compiling Main ( f.hs, interpreted )
f.hs:6:5:
Kind error: `F' is applied to too many type arguments
In the type `F Float Double'
In the type signature for `f':
f :: F Float Double
f.hs:9:5:
Kind error: `G' is applied to too many type arguments
In the type `G Float Double'
In the type signature for `g':
g :: G Float Double
Failed, modules loaded: none.

}}}
so I think that this has already been fixed. If you still think it's
broken, please reopen and attach a testcase.
