Re: [sv-ec] Class initialization proposal uploaded - Mantis 2597

Shalom,

I've uploaded a v3 propoal -- "...shall be provided automatically."  "
explicit or implicit new method...".


I think the redundancy in 8.16 is Ok since that is more explicitly
talking about the constructor chaining.  I did add an sentence referring
back to 8.7 for how property initialization occurs.
