What "publicity issue"?

No, Boost libraries should never use `assert` or `throw` directly (unless
they duplicate the relevant functionality of Assert and ThrowException.)

Note that an implementation consisting of e.g. `using std::latch;` does not
use `assert` or `throw` so it doesn't violate the above rule.

Interestingly, said implementation would actually fail our current
latch_test.cpp which uses BOOST_ENABLE_ASSERT_HANDLER to check
precondition violations, but we'll fix that test if we ever switch to it.
