.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
For aspects including timers and other Aspect::Advice::Around\-based
advice, recursion can be significant problem.
.PP
The \f(CW\*(C`highest\*(C'\fR 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.
