--------------------------------------+-------------------------------------
The overloaded strings extension isn't getting past core lint in the HEAD,
 e.g. test tc224:
 {{{
 *** Core Lint Errors: in result of Desugar ***
 <no location info>:
     In the expression: T.greet1 (GHC.Base.unpackCString# "hello")
     Argument value doesn't match argument type:
     Fun type: T.MyString -> T.MyString
     Arg type: [GHC.Base.Char]
     Arg: GHC.Base.unpackCString# "hello"
 *** Offending Program ***
 [...]
 }}}
