This is especially useful when an array is needed to initialize a class
member.

This uses a statement like

  array<T, 2> result = { t0, t1 };

to initialize the array.  This is correct and explicitly allowed by the
upcoming standard.  Unfortunately g++ warns about this with -Wmissing-braces
(which is implied by -Wall) because this relies on brace elision.  The report
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25137> has been filed more than
five years ago, but so far not much has happened.

the tested tuple is from Dune, std, or std::tr1.

For a tuple of references get() should still return a non-const reference,
even if the tuple itself is const:

  int n = 0;
  const tuple<int&> t(n);
  get<0>(t) = 1;  // post: n == 1

Without this property, tie() would be largely meaningless.

... with appropriate default parameters.  This leads to slightly
simpler code.  Note though that the method reportStream has
disappeared, and hence this patch may break some code.
I think that's acceptable, though, because the fix is trivial
and the reportStream method never appeared in a release.
