+PEAK-Rules is a highly-extensible framework for creating and using generic\
+functions, from the very simple to the very complex.  Out of the box, it\
+supports multiple-dispatch on positional arguments using tuples of types,\
+full predicate dispatch using strings containing Python expressions, and\
+CLOS-like method combining.  (But the framework allows you to mix and match\
+dispatch engines and custom method combinations, if you need or want to.)
