#24: Divide by Zero Signals Error (Clarification)

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
