NAME
       Aspect::Advice::After - Execute code after a function is called

SYNOPSIS
	 use Aspect;

	 after {
	     # Trace all returning calls to your module
	     print STDERR "Called my function " . $_->sub_name . "
";

	     # Suppress exceptions AND alter the results to foo()
	     if ( $_->short_name eq 'foo' ) {
		 if ( $_->exception ) {
		     $_->return_value(1);
		 } else {
		     $_->return_value( $_->return_value + 1 );
		 }
	     }

	 } call qr/^ MyModule::w+ $/

DESCRIPTION
       The "after" advice type is used to execute code after a function is called, regardless of whether or not the function returned normally or
       threw an exception.

       The "after" advice type should be used when you need to potentially make multiple different changes to the returned value or the thrown
       exception.

       If you only care about normally returned values you should use "returning" in the pointcut to exclude join points occuring due to
       exceptions.

       If you only care about handling exceptions you should use "throwing" in the pointcut to exclude join points occuring due to normal return.
