[Moved to DR at the May, 2015 meeting.]
Proposed resolution (November, 2014):
Change 11.4.5 [class.ctor] paragraph 4 as follows:
A default constructor for a class X is a constructor of class X that can be called without an argument. If there is no user-declared constructor for class X, a constructor having no parameters is implicitly declared as defaulted (9.5 [dcl.fct.def]). An implicitly-declared default constructor...
Change 188.8.131.52 [class.conv.ctor] paragraph 3 as follows:
A non-explicit copy/move constructor (_N4750_.15.8 [class.copy]) is a converting constructor. An implicitly-declared copy/move constructor is not an explicit constructor; it may be called for implicit type conversions.
Change _N4750_.15.8 [class.copy] paragraph 7 as follows:
If the class definition does not explicitly declare a copy constructor, one is declared implicitly. If the class...
Change _N4750_.15.8 [class.copy] paragraph 9 as follows:
If the definition of a class X does not explicitly declare a move constructor, one will be implicitly declared as defaulted if and only if...
It used to be clear that an implicitly-declared default constructor is not explicit. That has been inadvertently lost due to other changes, so this specification should be added to 11.4.5 [class.ctor] in parallel with the similar statement in _N4750_.15.8 [class.copy] paragraph 3.
