Proposed resolution:

Resolved by P0414R2, which was adopted in Issaquah.

Date: 2017-02-03.00:00:00

Addresses US 137

Paragraph (6.2): It is intuitive, but not specified, that the empty pointer returned by a dynamic_pointer_cast should point to null.

Proposed change:

Rephrase as:

Otherwise, shared_ptr<T>().
