There are some examples on issue #850 of using this feature, but they
are not easily found from the documentation. Adding them here as an
example makes them more findable and ensures they keep working if the
API changes.
--- Fixes ---
* Vector matchers now support initializer list literals better
--- Improvements ---
* Added support for `^` (bitwise xor) to `CHECK` and `REQUIRE`
--- Improvements ---
* Running tests in random order (`--order rand`) has been reworked significantly (#1908)
* Given same seed, all platforms now produce the same order
* Given same seed, the relative order of tests does not change if you select only a subset of them
* Vector matchers support custom allocators (#1909)
* `|` and `&` (bitwise or and bitwise and) are now supported in `CHECK` and `REQUIRE`
* The resulting type must be convertible to `bool`
--- Fixes ---
* Fixed computation of benchmarking column widths in ConsoleReporter (#1885, #1886)
* Suppressed clang-tidy's `cppcoreguidelines-pro-type-vararg` in assertions (#1901)
* It was a false positive trigered by the new warning support workaround
* Fixed bug in test specification parser handling of OR'd patterns using escaping (#1905)
--- Miscellaneous ---
* Worked around IBM XL's codegen bug (#1907)
* It would emit code for _destructors_ of temporaries in an unevaluated context
* Improved detection of stdlib's support for `std::uncaught_exceptions` (#1911)
Given that in the 2 or so years that matchers are thing nobody complained,
it seems that people do not actually write this sort of code, and the
possibility will be removed in v3. However, to avoid correctness bugs,
we will have to support this weird code in v2.
Unless someone steps up to fix the long link times with a set of
unobtrusive changes, the recommended solution will remain "use a better
linker".

Only works for exceptions that publicly derive from `std::exception`
and the matching is done exactly, including case and whitespace.
