You could simply do something like:
def hijacker(arg):
if I_feel_its_necessary:
return True, 1
else:
return False, 0
def my_function1(arg):
abort, code = hijiacker(something);
if abort: return code
... # Continue as normal
return 2
def my_function2(arg):
... # Maybe do some processing here
abort, code = hijiacker(whatever);
if abort: return code
... # Continue as normal
return 3
Although purists may frown upon the double return statement, it is still
a much cleaner code than using some magic to abort the caller function.
And tou have only to add two lines - always the same - at each function.
