-------------------------------+--------------------------------------------
For the uninitiated, Derive is an application of Template Haskell that can
 generate external Haskell code (depending on how you use it) instead of
 having it spliced into a module. Template Haskell was not designed for
 this, and it shows in the handling of qualified names. For example:

 {{{
 Prelude> '[]
 GHC.Base.[]
 Prelude> 'True
 GHC.Base.True
 Prelude> '(*)
 GHC.Num.*
 Prelude Data.Array.Unboxed> ''UArray
 Data.Array.Base.UArray
 }}}

 It would be nice if Template Haskell could instead use public names, where
 available, so that Derive and similar tools would be able to use qualified
 names (and the quoting syntax without fear of their ending up pointing
 into the middle of no-mans-land, or even GHC-only land.

 This would also mean that users of Derive via TH splicing wouldn't need to
 import so many modules that the derivings depend on.
