Current scheme: All functions which used to start with siL or L have been replaced by ones which pass arguments on the C stack. The special forms (eg Fprogn, Fsetq are still the same as before). Functions in the Lisp (resp Si package) are named fL... (respectively fS...) and they all pass arguments on the C stack and return multiple values, and have DEFUN's which specify their argd. eval still passes on the value stack All functions beginning with I pass on C stack. `
