Scala has the nice feature that if you write something like this: lst.map(_ - 1) It automatically rewrites to a function like this: lst.map(x => x - 1) This makes writing some higher-order functions much easier.
Of course, it's easy to make this using a macro and `#%app'. You can see the result here: github.com/samth/fancy-app I'm planning to put this in `unstable/app', and if there's interest I'll think about incorporating it into the default `#%app', after some experience with it. Lots of people have written similar things (`cut' in SRFI 26, Jay's `super-cut', etc), but I'd like to move towards using it implicitly. -- sam th sa...@ccs.neu.edu _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
