NotCPP.LookupValueName

This module uses scope lookup techniques to either export lookupValueName from Language.Haskell.TH, or define its own lookupValueName, which attempts to do the same job with just reify. This will sometimes fail, but if it succeeds it will give the answer that the real function would have given.

The idea is that if you use lookupValueName from this module, your client code will automatically use the best available name lookup mechanism. This means that e.g. scopeLookup can work very well on recent GHCs and less well but still somewhat usefully on older GHCs.
