I saw that the Ruby implementation in Netbeans is based
strongly on JRuby (parsing, errors et co). Due to this,
the Ruby/Rails support is the most advanced in NB (after Java,
the RoR one is the most advanced) - I suppose the developer (Tor),
could concentrate on features, not on parsing, and is
getting all JRuby improvements for free.
Wouldn't be this approach feasible for the IntelliJ Python plug-in too?
I mean JPython is live again and looks pretty good.
(I have no experience with IntelliJ language plug-ins, but I saw
the synergy in Netbeans, so it sounds logical that maybe it could
help IntelliJ too.)
