122. template-ids as unqualified-ids

Section: _N4567_.5.1.1  [expr.prim.general]     Status: CD1     Submitter: Mike Miller     Date: 3 June 1999

[Moved to DR at 10/01 meeting.]

_N4567_.5.1.1 [expr.prim.general] paragraph 11 reads,

A template-id shall be used as an unqualified-id only as specified in 13.9.3 [temp.explicit] , 13.9 [temp.spec] , and 13.7.6 [temp.spec.partial] .

What uses of template-ids as unqualified-ids is this supposed to prevent? And is the list of referenced sections correct/complete? For instance, what about 13.10.2 [temp.arg.explicit], "Explicit template argument specification?" Does its absence from the list in _N4567_.5.1.1 [expr.prim.general] paragraph 11 mean that "f<int>()" is ill-formed?

This is even more confusing when you recall that unqualified-ids are contained in qualified-ids:

qualified-id: ::opt nested-name-specifier templateopt unqualified-id

Is the wording intending to say "used as an unqualified-id that is not part of a qualified-id?" Or something else?

Proposed resolution (10/00):

Remove the referenced sentence altogether.
