Abstract

An efficient, logical and expressive type system supports the combination of refinement types and type membership expressions, as well as a top type that encompasses all valid values as members. A bidirectional type checking algorithm is provided for the type system including synthesis and checking steps to statically verify types of code based on the type system.
