About as much different as a Data.ByteString from an Array Int Char : there are several optimizations over a Data.Sequence.Seq that are specific to characters, for instance file IO using mmap, and the use of blocks (which would have been possible with about any constant size "Storable" type, of

As a user, I have too many HTML generators, a few of them with Ajax and none with server-side event handling (like ASPX or JSPX). Ajax is complicated but server side event handling is what I really miss because it is simple from the user point of view, my ervents could be handled in haskell code

Dear all, BlazeHtml started out on ZuriHac 2010. Now, Jasper Van der Jeugt is working on it as a student to Google Summer of Code for haskell.org. His mentors are Simon Meier and Johan Tibell. The goal is to create a high-performance HTML generation library. In the past few weeks, we have been ex
