It would be nice to have a DR # for this. In any case, if in practice the
compiler is already Ok, we can probably close it, right?

Agreed.  The wording in the standard should be fixed.

(In reply to comment #1)

I agree, I just recognize that 13.3.1.6 [over.match.ref] p. 1 b. 1 is written
to support this:

"The conversion functions of S and its base classes are considered, 
except that for copy-initialization, only the non-explicit conversion 
functions are considered. Those that are not hidden within S and yield
type “lvalue reference to cv2 T2” (when 8.5.3 requires an lvalue result) 
or “cv2 T2” or “rvalue reference to cv2 T2” (when 8.5.3 requires an rvalue 
result), where “cv1 T” is reference-compatible (8.5.3) with “cv2 T2”, are 
candidate functions."

IMO the core language should strike the reference to "implicit conversions" in
8.5.3.

This seems to me like a wording issue, not a compiler bug.  The use of
"implicitly" in 8.5.3 should have been adjusted when explicit conversion
operators went in; this should be reported as a core DR.
