#1727: Precedence and associativity rules ignored when mixing infix type and
data
constructors in a single expression
--------------------------------+-------------------------------------------
Reporter: [EMAIL PROTECTED] | Owner:
Type: bug | Status: new
Priority: normal | Milestone:
Component: Compiler (Parser) | Version: 6.6.1
Severity: minor | Keywords:
Difficulty: Unknown | Os: Unknown
Testcase: | Architecture: Unknown
--------------------------------+-------------------------------------------
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.
