mercury/tests/invalid/ambiguous_method_1.err_exp
Zoltan Somogyi bf8ffa632b Improve the wording of some diagnostics. 
compiler/check_typeclass.m:
    Improve the wording of several diagnostics, including

    - by using color more sparingly,
    - by making diagnostics complete sentences, and
    - by including an explicit "error:" prefix to signify a
      diagnostic's severity.

compiler/resolve_unify_functor.m:
    Improve the wording of a diagnostic.

ambiguous_method_1.m:022: In declaration for function `e'/0:
ambiguous_method_1.m:022: error in type class constraints: type variable `E'
ambiguous_method_1.m:022: occurs in the constraints, but is not determined by
ambiguous_method_1.m:022: the function's argument or result types.
ambiguous_method_1.m:022: All types occurring in typeclass constraints must
ambiguous_method_1.m:022: be fully determined. A type is fully determined if
ambiguous_method_1.m:022: one of the following holds:
ambiguous_method_1.m:022: 1) All type variables occurring in the type are
ambiguous_method_1.m:022: determined.
ambiguous_method_1.m:022: 2) The type occurs in a constraint argument, that
ambiguous_method_1.m:022: argument is in the range of some functional
ambiguous_method_1.m:022: dependency for that class, and the types in all of
ambiguous_method_1.m:022: the domain arguments for that functional dependency
ambiguous_method_1.m:022: are fully determined.
ambiguous_method_1.m:022: A type variable is determined if one of the
ambiguous_method_1.m:022: following holds:
ambiguous_method_1.m:022: 1) The type variable occurs in the argument types
ambiguous_method_1.m:022: of the predicate, function, or constructor which is
ambiguous_method_1.m:022: constrained.
ambiguous_method_1.m:022: 2) The type variable occurs in a type which is
ambiguous_method_1.m:022: fully determined.
ambiguous_method_1.m:022: See the "Functional dependencies" section of the
ambiguous_method_1.m:022: reference manual for details.
