-----------------------------------------+----------------------------------
The declaration
{{{
type Foo = [Int, String]
}}}
is accepted by GHC with no extensions enabled, while it is clearly invalid
Haskell. I didn't think about it but I suspect it has to do with
DataKinds stepping in when it shouldn't.
