272. Explicit destructor invocation and qualified-ids

Section: 11.4.7  [class.dtor]     Status: CD1     Submitter: Mike Miller     Date: 22 Feb 2001

[Moved to DR at 10/01 meeting.]

11.4.7 [class.dtor] paragraph 12 contains the following note:
an explicit destructor call must always be written using a member access operator (7.6.1.5 [expr.ref]); in particular, the unary-expression ~X() in a member function is not an explicit destructor call (7.6.2.2 [expr.unary.op]).

This note is incorrect, as an explicit destructor call can be written as a qualified-id, e.g., X::~X(), which does not use a member access operator.

Proposed resolution (04/01):

Change 11.4.7 [class.dtor] paragraph 12 as follows:

[Note: an explicit destructor call must always be written using a member access operator (7.6.1.5 [expr.ref]) or a qualified-id (_N4567_.5.1.1 [expr.prim.general]); in particular, the unary-expression ~X() in a member function is not an explicit destructor call (7.6.2.2 [expr.unary.op]).]
