A framework for program development based on schematic proof

Often, calculi for manipulating and reasoning about programs can be recast as calculi for synthesizing programs.The dierence involves often only a slight shift of perspective: admitting metavariables into proofs.We propose that such calculi should be implemented in logical frameworks that support this kind of proof construction and that such an implementation can unify program veri cation and synthesis.Our proposal is illustrated with a worked example developed in Paulson's Isabelle system.We also give examples of existent calculi that are closely related to the methodology we are proposing and others that can be pro tably recast using our approach.
