Bob Green asks for a function that returns the number of arguments of a
function.  since the number of valid arguments is not a single number for

provide one.  however, the lambda list is usually available, one way or the
other.  ANSI Common Lisp provides `function-lambda-expression', the
documentation of which you will find at
