> Issue summary
> -------------
> 
>  #ClassFileModuleName --- The name of a module is not a simple UTF-8
>  string but is, rather, derived from the value of the `this_class`
>  field of the `ClassFile` structure, which is awkward. [1]
> 
> Proposal
> --------
> 
> Revise the binary form of module declarations [2] as follows:
> 
>  - Add a `u2 module_name_index` field to the `Module` class-file
>    attribute, immediately preceding the existing `module_flags` field.
>    The value of this field will be the index of a `CONSTANT_Utf8_info`
>    structure in the constant pool that represents the module's name in
>    internal form, i.e., with period characters replaced by slashes [3].
> 
>  - Rather than encode the module's name in the value of the `this_class`
>    field of the `ClassFile` structure, simply set this field to zero.
> 
> (Side note: The prototype implementation does not store module names in
> internal form, even though the draft specification [2] has long mandated
> that.  The implementation will be fixed.)
