Comment(by StephenBlackheath):

 Here's the error that the wrong generated code {{{Filter -1}}} produces,
 because there need to be parentheses around (-1).

 {{{
 libraries/base/GHC/Event/KQueue.hsc:201:17:
     Couldn't match expected type ‛Filter’
                 with actual type ‛Word16 -> Filter’
     In the first argument of ‛(-)’, namely ‛Filter’
     In the expression: Filter - 1
     In an equation for ‛filterRead’: filterRead = Filter - 1

 libraries/base/GHC/Event/KQueue.hsc:203:17:
