Both extensions are often performed in quotient constructions. To ease the work involved with such quotient constructions, we re-implemented in Isabelle/HOL the quotient package by Homeier.

Like his +package, we designed our quotient package so that every step in a quotient construction can be performed separately and as a result we are able to specify completely the procedure of lifting theorems from the raw level to the quotient level. The importance for programming language research is that many properties of
