      whyml: include pure symbols in the program namespace · 55c1fc02
      Andrei Paskevich authored
      Thus, we do not need to look through two different namespaces.
      The only difference w.r.t. the core namespace semantics is that
      a program symbol (pvsymbol, psymbol, plsymbol, or xsymbol) may
      be introduced in the scope of an lsymbol of the same name and
      overshadow it in program expressions, though not in specifications.
      For example, the following declarations allow to use (!) both in
      programs and specifications:
      
          type ref 'a = {| mutable contents : 'a |}
          function (!) (x: ref 'a) : 'a = x.contents
          let (!) (r: ref 'a) = {} r.contents { result = !r }
      
      Notice, however, that itsymbols cannot overshadow pure tsymbols.

      whyml: do not count the used symbols in program declarations · d7477cf4
      Andrei Paskevich authored
      It is difficult to count all the used symbols in programs.
      On the other hand, the pure API already cares about the missing
      symbols in verification conditions. So we relieve the program API
      of this duty, and trust typechecking (and any other API user) to
      not forget to add all the necessary dependencies to a module.
      
      The worst possible outcome, it seems, is that one can extract
      an ill-formed OCaml code if the WhyML module is done via the API,
      and VCs were not generated.
