Version 1, January 1994

This design note specifies that division by zero signals an error.  This 
makes Dylan programs safer and more robust, possibly at the cost of speed 
in some cases.

-------------------------------------------------------------------

Specify that division by zero signals an error. The special case 0/0 is 
also specifically an error. This affects the following functions (p.
149-150):

/ unary/ binary/ 
floor/ ceiling/ round/ truncate/
modulo remainder
