I've also noticed that I can write

data X = X deriving Show

But not

import Prelude hiding print

But we can write

x :: Foo x => …
x :: (Foo x) => …

Can write

class X

But not

module X

I wouldn't expect that there are particular argued reasons for these
inconsistencies. It's difficult to balance a consistent syntax in a
language while trying to be convenient. I don't think it matters too
much.
