Type synonyms not expanded consistently in errors
With this module:
type Foo = Int
x :: Char
x = f
f :: Foo
f = 5
GHC says:
g.hs:5:5:
Couldn't match expected type `Char' with actual type `Int'
Expected type: Char
Actual type: Foo
In the expression: f
In an equation for `x': x = f
Note that the first line talks about Int
, whereas the third line talks about Foo
. I'd expect both to talk about Foo
.
