My idea would be reusing some of the already-available tools for compiling Haskell to JS (for example, UHC), and develop with any of them a complete library for client-side scripting; rather that redevelop a way to compile Haskell to JS.
I think it's really a pity not being able to use things like what Yesod provides in a client-side context. And both sides would benefit: they can share common code for datatypes (as it's done in Google Web Toolkit), and autogenerate some code for sending or receiving AJAX requests, for example. 2012/3/6 Michael Snoyman <mich...@snoyman.com> > On Tue, Mar 6, 2012 at 11:40 PM, Alejandro Serrano Mena > <trup...@gmail.com> wrote: > > Hi, > > I'm really looking forward to helping in the Summer of Code, if Haskell > goes > > into it this year (something I take for granted :).
