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: http://users.skynet.be/jyp/DData/doc/index.html while the source code is at http://users.skynet.be/jyp/DData/ddata.tar.gz Any comment is welcome. (Including "I support this proposal" :)) Cheers, JP. PS. 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 system * 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 __________________________________ Do you Yahoo!?
