By the way, it is not true that folding in Scribble only works for C/C++. Actually, this depends on the lexer for that particular language. It could however be true that the E lexer does not have this functionality (I'm not at home so I can't check at the moment). If so, this could probably be added without too much difficulty (better ask Leif who wrote this lexer). It would also be possible to improve other aspects of E support but I don't have the time to work on this myself.
