This is genericserialize, a library of functions using the "Scrap your
boilerplate" framework to serialize arbitrary data.

Basic usage:

*Data.Generics.Serialization.SExp> buildList (sexpSerialize (True,False))
"(~l,~r #t #f)"
*Data.Generics.Serialization.SExp> buildList (sexpSerialize [True,False])
"(#t #f)"
*Data.Generics.Serialization.SExp> buildList (sexpSerialize (Just "help"))
"(Just \"help\")"
*Data.Generics.Serialization.SExp> withList (sexpDeserialize) "(#t #f)" :: Maybe [Bool]
Just [True,False]
*Data.Generics.Serialization.SExp> withList (sexpDeserialize) "(Just \"f\\oo\")" :: Maybe (Maybe Bool)
Nothing
*Data.Generics.Serialization.SExp> withList (sexpDeserialize) "(Just \"f\\oo\")" :: Maybe (Maybe String)
Just (Just "foo")
*Data.Generics.Serialization.SExp>
