   While fooling around with MIT Scheme 7.1, found this interesesting phenomena.
   Apparently, multidigit numbrs are not self evaluating, they need to go through
   adds (+) and multiplies (*) in order to evaluate.

My guess is that the reader uses + to add up the digits of a multi-digit
number.  This doesn't mean that such numbers aren't self-evaluating.
They are.  It just means that + is used to convert them from text to
objects.
