The traverse-with-class package

[ Tags: data, library, mit ] [ Propose Tags ]

This is a generic programming library in the spirit of "Scrap your boilerplate with class", but with several improvements — most notably, it's based on the gtraverse function instead of gfoldl. gtraverse is equivalent in power to gfoldl, but lets you more easily write non-standard views of the data type.
