- displaying the arglist and namespace of procedure at point
http://synthcode.com/emacs/scheme-complete.el provides lexically-scoped tab completion using a limited type inference, which significantly reduces the number of symbols to complete. It also can optionally show the arglist of the procedure at point in the modeline. It works with any R5RS Scheme, but would need some work to support Gambit's namespaces (and the code is a hideous mess).
