Excellent.

Earlier today I added the C++0x versions of the existing
tr1::reference_wrapper tests + the testcase from libstdc++/24803 (which
I assigned to myself, but only tentatively): while we are touching
reference_wrapper too, we should make sure not to regress, and, if
possible, we should also fix 24803 (the minimal version). Can you double
check your existing patch vs the 3 additional testcases? And / or we can
imagine splitting out the reference_wrapper changes... probably I'm Ok
with any plan you may want to suggest... Just let me know...

Thanks,
Paolo.
