This month, Phil Freeman will present"Principal type-schemes for functional programs (http://web.cs.wpi.edu/~cs4536/c12/milner-damas_principal_types.pdf)" by Damas and Milner.
The Damas-Hindley-Milner type system is a classical system for the first-order polymorphic lambda calculus, and the ML family of programming languages. This paper introduces Algorithm W, a simple algorithm for type reconstruction in the DHM type system. I'll walk through the main results of the paper, and compare the DHM type system with other more modern systems.
