This PR introduces a Hoare logic for monadic programs in
Std.Do.Triple, and assorted tactics:mspecfor applying Hoare triple specificationsmvcgento turn a Hoare triple proof obligation⦃P⦄ prog ⦃Q⦄into pure verification conditoins (i.e., without any traces of Hoare triples or weakest preconditions reminiscent ofprog). The resulting verification conditions in the stateful logic ofStd.Do.SPredcan be discharged manually with the tactics coming with its custom proof mode or with automation such assimpandgrind.This is pre-release of a planned feature and not yet intended for production use. We are grateful for feedback of early adopters, though.
