#5379: Scoping error in Template Haskell antiquotations
---------------------------------+------------------------------------------
Reporter: reinerp | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler

Os: Unknown/Multiple | Blocking:
Architecture: Unknown/Multiple | Failure: None/Unknown
---------------------------------+------------------------------------------
Related to #5375, #5037. When compiling and running the following:
{{{
{-# LANGUAGE TemplateHaskell #-}
import Language.Haskell.TH
$( [d| g = 0
h = $( return $ LamE [VarP (mkName "g")] (VarE 'g) ) |] )
main = print (h 1)
}}}
the splice should be
{{{
g' = 0
h = \g -> g'
}}}
and so the program should print 0 at runtime. Instead, it prints 1.
This is with both ghc-7.0.3 and ghc-7.3.20110803.
