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.
