Pretty printing: Strict record fields are not parenthesized properly
When I type in GHCi:
λ> data Foo = Foo { x :: !(Maybe Int) }
λ> :i Foo
data Foo = Foo {x :: !Maybe Int} -- Defined at <interactive>:71:1
But this is not legal Haskell syntax:
λ> data Foo = Foo {x :: !Maybe Int}
<interactive>:73:22: error:
• Unexpected strictness annotation: !Maybe
• In the type ‘!Maybe Int’
In the definition of data constructor ‘Foo’
In the data declaration for ‘Foo’
I think it should be pretty printed with parens:
λ> :i Foo
data Foo = Foo {x :: !(Maybe Int)} -- Defined at <interactive>:71:1
