INFIX: Infix reader macro for Common Lisp.

This is an implementation of an infix reader macro. It allows the user to type arithmetic expressions in the traditional way (e.g., 1+2) when writing Lisp programs instead of using the normal Lisp syntax (e.g., (+ 1 2)). It is not intended to be a full replacement for the normal Lisp syntax. If you want a more complete alternate syntax for Lisp, get a copy Apple's MLisp or Pratt's CGOL. Although similar in concept to the Symbolics infix reader (#), no real effort has been made to ensure compatibility beyond coverage of at least the same set of basic arithmetic operators. There are several differences in the syntax beyond just the choice of #I as the macro character. (Our syntax is a little bit more C-like than the Symbolics macro in addition to some more subtle differences.) We initially chose $ as a macro character because of its association with mathematics in LaTeX, but unfortunately that character is already used in MCL. We switched to #I() because it was one of the few options remaining. Documentation included at the top of the source file. Examples and testing routines at the end.
