60. Reference binding and valid conversion sequences

Section: 12.2.4.2.5  [over.ics.ref]     Status: CD1     Submitter: Steve Adamczyk     Date: 13 Oct 1998

[Moved to DR at October 2002 meeting.]

Does dropping a cv-qualifier on a reference binding prevent the binding as far as overload resolution is concerned? Paragraph 4 says "Other restrictions on binding a reference to a particular argument do not affect the formation of a conversion sequence." This was intended to refer to things like access checking, but some readers have taken that to mean that any aspects of reference binding not mentioned in this section do not preclude the binding.

Proposed resolution (10/01):

In 12.2.4.2.5 [over.ics.ref] paragraph 4 add the indicated text:

Other restrictions on binding a reference to a particular argument that are not based on the types of the reference and the argument do not affect the formation of a standard conversion sequence, however.
