nice..had an idea of a browser engine powered by a different scripting language like Lisp. Even better, a browser engine that can plug in any language runtime through which web apps can be coded (WebAssembly is working in that direction to provide a single portable runtime I think).
Makes me nostalgic for pentadactyl (the IMHO superior fork of Vimperator- both of which are discontinued)
