The status table at was generated
with an experimental version of the status table software.

It adds a new possible result, "note", which is in addition to the usual
"pass", "fail", or "warn" results.

As a trial of the feature, John Maddock has modified type traits
is_class_test to detect intrinsic compiler support for type traits, and
issue a "note" if it isn't present. (In the past, this test always reported
"fail" for compilers without intrinsic support, but that didn't really
capture the situation.)

As a result of the new feature, the is_class_test results for several
compilers now report "pass, note", hyperlinked. If you click through, you
get the note produced by the test program:

This compiler version does not provide support for is_class on union types.
Such support is not currently required by the C++ Standard. It will be
required to support the upcoming Standard Library Technical Report.

At the moment, the only other test which needs to make use of this feature
to be able to accurately report "pass, note" is type traits is_union_test.
Other tests might use the feature for other purposes.
