Fail creating class instances with functions taking just one argument of type NameBlock

[Víctor de Buen Remiro]

When we try to create an instance of a class by means of a function taking just one argument of type NameBlock TOL shows an stupid error and doesn't creates it.

  Class ClassA 
  {
    Text _.name;
    Real _.length
  };

  ClassA ClassA.New(NameBlock args)
  {
    ClassA a = [[
      Text _.name   = args::name,
      Real _.length = TextLength(args::name)
    ]]
  };

  ClassA a = ClassA.New([[Text name="lkshfli", Real k= 1]]);
