Class description
The class of tuples. This class is further partitioned into disjoint subclasses; each tuple shape defined by TUPLE: is a new class.

Tuple classes have additional word properties:
"predicate" - a quotation which tests if the top of the stack is an instance of this tuple class
"slots" - a sequence of slot-spec instances
"layout" - an array with the tuple size and superclasses encoded in a format amneable to fast method dispatch
