PEAK-Rules is a highly-extensible framework for creating and using generic functions in Python. . PEAK-Rules supports out of the box: multiple-dispatch on positional arguments using tuples of types, full predicate dispatch using strings containing Python expressions, and CLOS-like method combining. Additionally, PEAK-Rules allows to mix and match dispatch engines and custom method combinations. . This package also provides some third party contribution over PEAK-Rules, in particular: . * prioritized_methods - prioritize methods to resolve dispatch ambiguities
