[Haskell] RFC: DData in hierarchical libraries

Dear haskellers,

I propose to add a modified version of DData to the
hierachical libraries.

DData is a concrete library of collection types, by
Daan Leijen.
My modifications intend to make DData fit better in
the hierarchical libraries.

The haddock-generated documentation can be found here:

Any comment is welcome. (Including "I support this
proposal" :))


For those who don't follow the libraries list, the
reasoning leading to this proposal goes as such:

* Data.FiniteMap & Data.Set don't use the module
* We need better collection types
* A fully fledged collection framework is difficult to
agree on for integration in standard.
* We should have a concrete types library, leaving the
framework for later.
* DData looks like a good candidate
