I was just studying this stuff and reviewing this patch with fresh eyes, and it seems to me that it is actually incorrect. This changes the execution logic so as stmt_beg and stmt_end are called additionally each time a function, a trigger or an event trigger is executed. If one looks closely at the code, he/she could notice that func_beg and func_end are already present as hook points to watch what is happening in the execution, as these are here to give entry points for execution functions, so it seems to me that we don't need extra watch calls as proposed, because there is already everything needed, and that the current points are correct. -- Michael
