The idea was to to give people looking at the test results an accurate
view of the usefulness of FOREACH on a certain compiler. If the
"rvalue_const" test appears to pass for vc7.1, it'll give people a false
sense of security. (Because, as we all know, nobody reads the
documentation.) Once I have marked this failure as expected, which I'm
working on now, all will be right with the world.
On a compliant compiler, this should Just Work; that is, you should be
able to iterate over a const rvalue sequence.
