59. Clarification of overloading and UDC to reference type

Section: 12.2.2.5  [over.match.copy]     Status: TC1     Submitter: Steve Adamczyk     Date: 13 Oct 1998

Sections 12.2.2.5 [over.match.copy] and 12.2.2.6 [over.match.conv] should be clarified regarding the treatment of conversion functions which return reference types.

Proposed resolution (10/99):

In 12.2.2.5 [over.match.copy] paragraph 1, change

Conversion functions that return "reference to T" return lvalues of type T and are therefore considered to yield T for this process of selecting candidate functions.
to
Conversion functions that return "reference to X" return lvalues of type X and are therefore considered to yield X for this process of selecting candidate functions.
In 12.2.2.6 [over.match.conv] paragraph 1, change
Conversion functions that return "reference to T" return lvalues of type T and are therefore considered to yield T for this process of selecting candidate functions.
to
Conversion functions that return "reference to cv2 X" return lvalues of type "cv2 X" and are therefore considered to yield X for this process of selecting candidate functions.
