This is a GNUstep problem, I believe. The problem is that unrecognised selectors enter GNUstep's forwarding mechanism, which then attempts to use typed selector info to construct an NSInvocation instance. I believe the correct thing for it to do is assume that every method that does not have type information available is to assume that it takes id and has id arguments, but instead it throws an exception. I'll try to patch GNUstep to fall back to a 'count the colons' strategy. > Cascade ';' Needs a new AST node class with a single receiver expression and a list of message expressions.

All that's needed is a ten line bit of glue code to join the two together.

Writing collection related code in ObjC > style does the trick for now ;-) map:, foreach:, select: and fold: are implemented on NSArray. None are implemented on NSDictionary (patches welcome!) or NSSet yet though. I also haven't added F-Script-style dictionary literal parsing support, which I would like for 1.0 (although it's not in the todo list).
