   Well there is of course this https://github.com/purescript/purescript-in-purescript which is outdated. I don't think it's a good idea to develop in parallel a parser to the official purescript parser which is in the purescript compiler. Instead i would prefer import / export of the syntax tree.

   For codegen the purescript code tree would be constructed directly, so we don't need a parser.

   Would be interesting though (for testing as well) to do:

   1. create arbitrary code structures (AST / CST) with Arbitrary instance from haskell quickcheck
   2. export to intermediate format (not clear which format is suitable)
   3. import into this library
   4. pretty print with purescript code
   5. read printed source file with official purescript parser in purescript compiler
   6. compare structures for equility

   By the way .. i vaguely remember that there were some parts to split of some parts of the official purescript compiler into their own library ... this might become interesting in the future.
