COMP3161/COMP9164 Supplementary Lecture Notes Type Inference Liam O’Connor December 10, 2019 Explicitly typed polymorphic languages, where the user must make explicit type abstractions and applications, such as the version of MinHS introduced with parametric polymorphism, are very awkward to use in practice. Ideally, we would like to leave these type annotations implicit, and have the
