RE: [sv-bc] DataTypes: wording for optional "var"

Please, I don't want to have to write

   var logic [3:0] count;

instead of

   var [3:0] count;

Just as I don't have to write

   wire logic [3:0] w;

I'll be sending out a revised BNF in a few minutes to fix the
problem Mark pointed out.

Hi Kathy,

I think it's a good time to introduce "var".

I only have one issue with this proposal:
What is the point of allowing an "optional" data type after var?
There are no backward compatability issues to deal with.
If there is no good reason for this optionality, I would prefer
that the LRM mandate the use of a data type after the var keyword.

Regards,
Doug
