Leon Gondelman 0d210cae04 first step toward cons-union iso: construction of min function for FSet A, where A is Totally Ordered. To construct min, various lemmas about empty set are needed. This min function is constructed in a very inefficient way w.r.t. proofs of assoc, comm, etc. 2017-06-03 00:08:12 +02:00
