Proposed resolution:

This issue is resolved by the resolution of issue 1435.

Note that destructors suffer from similar problems as those of constructors dealt with in issue 194 and in 263 (constructors as friends). Also, the wording in 11.4.7 [class.dtor], paragraph 1 does not permit a destructor to be defined outside of the memberlist.

Change 11.4.7 [class.dtor], paragraph 1 from

...A special declarator syntax using an optional function-specifier (9.2.3 [dcl.fct.spec]) followed by ~ followed by the destructor's class name followed by an empty parameter list is used to declare the destructor in a class definition. In such a declaration, the ~ followed by the destructor's class name can be enclosed in optional parentheses; such parentheses are ignored....

...A special declarator syntax using an optional sequence of function-specifiers (9.2.3 [dcl.fct.spec]), an optional friend keyword, an optional sequence of function-specifiers (9.2.3 [dcl.fct.spec]) followed by an optional :: scope-resolution-operator followed by an optional nested-name-specifier followed by ~ followed by the destructor's class name followed by an empty parameter list is used to declare the destructor. The optional nested-name-specifier shall not be specified in the declaration of a destructor within the member-list of the class of which the destructor is a member. In such a declaration, the optional :: scope-resolution-operator followed by an optional nested-name-specifier followed by ~ followed by the destructor's class name can be enclosed in optional parentheses; such parentheses are ignored....
