Re: EXTERNAL: RE: [vhdl-200x] Records with directional subtypes

This has been a great discussion. However, I was out for a while and now
find myself unable to parse all the messages that have transpired. Could
someone send out a summary of the proposed syntax/semantics so the chain
can converge at a new point?

If the compiler folks can make the named mode happen,
that would be my preference too. Peter expressed concern
about this in the context of port declarations.
