Unreserved keywords are one approach, though I'm not aware if they come with any 
negatives. Then the question becomes which reserved words could become 
unreserved keywords. (This can be restricted to reserved words related to 
tasking/concurrency to avoid going through all the reserved words.)

Does that imply that the voting has since changed and such a proposal might now 
be accepted?

I agree that the ARG has done a good job in reusing reserved words in many 
cases, "with" being the most obvious. I concentrated on tasking/concurrency 
reserved words since that seems to be an exception.
