WRT the the updates/additions, I would like to see the
work that is done get incorporated. In the VHDL-200X
fast track time frame, other work could be considered if
someone is willing to work the issues. The VHDL-200X
fast track is facilitating completion of some of the issues,
such as, how to handle logic reduction operators
(see FT2) and for the numeric_???_unsigned how to handle
comparison operators (see FT1).

Since you are leading this subgroup, what do you think
should be done? Minimally I would hope that there is
some degree of coordination with VHDL-200X DTA proposals.
I would be open to integrating it, however, where would
the leave the parallel Verilog effort? Would it be its
own standard?

What is the status of FPHDL? I noticed that you were
soliciting for Beta VHDL testers. How about on the Verilog
side, is it as mature as the VHDL side?

I have heard people mention "trial standards". Perhaps
FPHDL would be approproiate as a trial standard for its
first revision and then when it stabilizes it could
be integrated as part of 1076 in VHDL-200X phase 3 (2?).
