Add around (try-finally) with DO action on enter and DO action on finally

It would be very helpfull to inject an action in the entry point of a method, then another in the exit of the method, and share binding variables between both action

Here is 2 typical usages:

1/  compute endTime-startTime, and add logs or increments timing statistics
 

// DO ENTER code {{
long startTime = System.currentTimeMillis();
// }}
try {
   .... the instrumented method
} finally {
   // DO EXIT code {{
   long elapsedMillis = System.currentTimeMillis() - startTime;
   log.info("executed method, took " + elapsedMillis + " ms");
   // }}
}

2/ push then pop values in a ThreadLocal object

// DO ENTER code {{
ThreadLocal someThreadLocal = ...
Object prevValue = someThreadLocal.get();
someThreadLocal.set(somePushedValue);
// }}
try {
   .... the instrumented method
} finally {
   // DO EXIT code {{
   someThreadLocal.set(prevValue );
   // }}
}

In these 2 samples, it is not possible to use 2 different rules with "ENTER" and "EXIT" method, because we have to use a common "BINDING" between 2 blocks of code
