Re: [sv-ec] class construction syntax - new feature proposal

This could be considered for the next PAR.  1800-2009 is closed
for such changes.  So the earliest this would be introduced
would likely be 2012 or so.

This would be syntactically identical to the copying constructor
and I might object to that since it might be fairly confusing.
I'm not going to take a position at this point.
