Hi Mark,

>What if it fails inside of Block and an error handler pick up an error? will it still work in the way you are showing?

No, TRY..CATCH and error handlers are completely different concept that don't mix very well on a greater scale. If your code block calls methods of object that have error handlers, the error hander is executed. You would need to add code to the error handler that throws an exception in this case. You probably need some sort of flag to trigger this behavior, such as a private variable or a configuration file.
