Re: arguments hint

[Richard Stallman]

    Is there a mode for Emacs that gives hints on function
    arguments?  For instance, I type

      int result = function(

    and immediatly after '(' is typed, Emacs shows in a
    small window:

      int
      function(int x, int y, int z)

Whether a feature like this already exists in Emacs, I don't know.
But it sounds useful.
