GHC 7.2.1 - Template Haskell Bug
Fresh GHC 7.2.1 cannot compile
{-# LANGUAGE TemplateHaskell #-}
module Foobar where
foobar :: Int
foobar = $([|
let
bar :: Int
bar = 5
in bar
|])complaining that "The type signature for `bar' lacks an accompanying binding".
Neither GHC 6.xx nor GHC 7.0.x had this bug.
