Precedence and associativity rules ignored when mixing infix type and data constructors in a single expression
The following code:
infixr 5 `Foo`
infixr 6 `Bar`
data a `Foo` b = a `FOO` a `Bar` b
data a `Bar` b = a `BAR` b
fails to compile, ignoring the fixity declarations. It should be parsed as a FOO
(a Bar
b) but currently the parentheses are required, which misses the point of fixity annotations.
