Frankly, I'm not 100% sure we want an error here: I mean, we have a Requires
violation in the case at issue, which, in general, in my reading of the
standard, certainly doesn't mean the code must not compile, means

I understand your concern here, which is why I wrote that I thought that it was
implicit.
The standard says where geti(t) == geti(u) is a valid expression only,
however; 6.1.3.4 says that geti(t) is ill formed if I is

(In reply to comment #3)
To me, if geti(t) fails to compile under the assumption of ill formed,
then
by the definitions of 6.1.3.5, geti(t) == geti(u) should also fail to
compile. Although it is not explicitly stated

By the way, in the meanwhile I checked N2322 and C++0x will simply enforce
EqualityComparableTTypes, UTypes...
We are presently trying to figure out whether in the meanwhile we want to
explicitly enforce sizeof...(TTypes)

While I agree that this is an issue of implementation detail, I thought there
was code already there to stop this case, except it is broken :(
Looking at the svn copy of tr1/tuple, you can see operator== (and others)

Cool, if everything can be dealt with right now by simply fixing that, then
let's do it! Really, in these times, I dislike the idea of robustify templates
here and there (without a global neat strategy) with old-times
