The Generic-Arithmetic-Dylan module imports and reexports all of the interfaces exported by the dylan-excluding-arithmetic module and the generic-arithmetic module.
The dylan-excluding-arithmetic, dylan-arithmetic, and generic-arithmetic modules provide convenient building blocks for programmers to build the particular set of global name bindings they wish to work with. The purpose of the generic-arithmetic-dylan module is to provide a standard environment in which generic arithmetic is the norm, for those programmers who might want that.
