Don't warn about pattern-bindings of the form `let !_ = rhs`
With GHC 7.8.2, code like
let !_ = rqPostParams rq
let !_ = rqParams rq
triggers the following warnings:
src/Snap/Internal/Test/RequestBuilder.hs:150:13: Warning:
This pattern-binding binds no variables: !_ = rqPostParams rq
src/Snap/Internal/Test/RequestBuilder.hs:151:13: Warning:
This pattern-binding binds no variables: !_ = rqParams rq
I think that let !_ = rhs
shouldn't trigger a warning, just like let _ = rhs
doesn't.
