Hask is a pure-Python, zero-dependencies library that mimics most of the core language tools from Haskell, including: Full Hindley-Milner type system (with typeclasses) that will typecheck any function decorated with a Hask type signature. Easy creation of new algebraic data types and new typeclasses, with Haskell-like syntax.

I'm frustrated with that because as I mentioned already, switching from rtype to Hindley-Milner or vice verse, we lose a lot of valuable information.

It is also known as Damas–Milner or Damas–Hindley–Milner. It was first described by J. Roger Hindley and later rediscovered by Robin Milner. Luis Damas contributed a close … Visa mer As a type inference method, Hindley–Milner is able to deduce the types of variables, expressions and functions from programs written in an entirely untyped style. Being scope sensitive, it is not limited to … Visa mer Now that the deduction system of HM is at hand, one could present an algorithm and validate it with respect to the rules. Alternatively, it might be possible to derive it by taking a closer … Visa mer In the previous section, while sketching the algorithm its proof was hinted at with metalogical argumentation. While this leads to an efficient algorithm J, it is not clear whether the … Visa mer • A literate Haskell implementation of Algorithm W along with its source code on GitHub. • A simple implementation of Hindley-Milner algorithm in Python Visa mer The remainder of this article proceeds as follows: • The HM type system is defined. This is done by describing … Visa mer The type system can be formally described by syntax rules that fix a language for the expressions, types, etc. The presentation here of such a syntax is not too formal, in that it is written down not to study the surface grammar, but rather the Visa mer Recursive definitions To make programming practical recursive functions are needed.
