  * Parse import/export of named fields more correctly.
    * The compiler previously rejected export/import of a mixture of
      explicit field names and constructor names as subordinates of a
      type name.  Now we accept it.
    * The import/export decl  TC(a,b,c...)  is ambiguous, because it
      could be a class with methods, or a type with only field names
      mentioned.  Thus, there is no point in distinguishing them in the
      abstract syntax - they are sorted out in a later analysis anyway,
      in exactly the same way as the TC(..) form.
    * The .hx file mechanism now knows about field names and records them.
