This library is inspired by HList[2], and interfaces are stealed from data-accessors[3]. And lenses[4], fclabels[5], and records[6] devote themselves to similar purposes.

Enjoy!

Which niche does `has' fit between extensible (and more complicated) records like HList and records vs the libraries that provide only accessors? It would be nice to have some summary of the features of each, ex. lenses, fclabels and data-accessor do not permit record extension (which has seems to do). -- Adam
