      Do not add constraints of the form s <= 'a <= t, for monomorphic alpha's, just check that the constraint holds for all substitution and replace it with a universal Sat or Unsat. This prevent the algorithm from introducing dummy substitutions later on of the form 'a <- 'a which interact badly with type cleaning (replacing covariant/contra-variant occurences by Empty/Any).

      Make fresh variables really fresh · c9ad3e5c
      Pietro Abate authored
      Add a global variable table, so when we call "Var.mk id" twice, the
      same variable is returned and when we call "Var.fresh v" we always
      return a truly globally fresh variable.

      More var.ml cleanup · 737730a2
      Pietro Abate authored
      - Var identifiers are now of type U.t instead of string
      - Remove TVar from ast. Polymorphic variables are just types

      Parse type variables as patterns · 6ee8a6b0
      Pietro Abate authored
      - type variables are now correctly parsed as patterns
        and not as expressions
      
      - Add a new module Var that contains all the type variables
        related machinery
      
      - Remove old functions and unit tests about BoolVar of only
        variables, since now variables are always stored associated
        with one or more kinds
