also there's RubyJS: http://rubyforge.org/projects/rubyjs/ it's again a javascript compiler - ruby to javascript - and the beginnings of a port of GWT to Ruby, called rwt. this project _definitely_ needs more attention. michael's talk (included in the docs/) shows that he has spent considerable effort in ensuring that not only is the compiler faithful to the features of ruby, but also that the features are translated _efficiently_. which takes a hell of a lot of doing. the nice thing about michael's work is that he's leading the way in showing the pyjamas compiler how it _really_ should be done. pyjamas is capable of running a very significant amount of python, but it _is_ missing some crucial features: **kwargs for example, and the 0.4 release has just added a _very_ basic type of exception handling. that having been said: for the majority of purposes - most web development - pyjamas is _more_ than adequate. as a general-purpose plugin replacement for /usr/bin/python, however, it's not quite there. and, given that javascript cheerfully goes about its way with the "undefined" concept, it's always going to be a _bit_ tricky to provide absolutely _every_ language feature, faithfully. that having been said, the speedup factor of pyv8 should make the pyjamas compiler a _really_ attractive option, and i think that when it becomes the "norm" to have a javascript interpreter as part of a sysadmin's / developer's dailiy life in the same way that /usr/bin/ perl and /usr/bin/python are, then compilers like RubyJS, Pyjamas and GWT will have a much bigger significance. l. -- http://mail.python.org/mailman/listinfo/python-list
