5167,Allow proto::extends default ctor to leave the proto_expr_ member uninitialized,antoine.de-maricourt@…,Eric Niebler,"Proposal:

turn default ctor for proto::extends in proto/extends.hpp
from:
  
{{{
extends(): proto_expr_(){}
}}}

to: 
 
{{{
 extends() { }
}}}


Rational:
It is up to the derived class to decide if expr can be left in undefined state (and to control it), and not to the extends base class.
