=head1 DESCRIPTION

For aspects including timers and other L<Aspect::Advice::Around|around>-based
advice, recursion can be significant problem.

The C<highest> pointcut solves this problem by matching only on the highest
invocation of a function. If the function is called again recursively within
the first call, at any depth, the deeper calls will be not match and the
advice will not be executed.
