Abstract
This is an exercise in the description of programming languages as indexed categories. Type classes have been introduced into functional programming languages to provide a uniform framework for ‘overloading’. We establish a correspondence between type classes and comprehension schemata in categories. Coherence results allow us to describe subclasses and implicit conversions between types.
