You know you can simply pass functions as parameters, right? def lock(func, *args): # ...setup result = func(*args) #... teardown return result. And then, with 3 more lines you do a decorator out of that def locked(func): # <'lock' body as above> return lock in the end: @locked def mythings(): # code that runs 'locked' ...

Today I think about lambda in Python and what if we introduce the new syntax: ```python def lock(*args, closure): # Do some stuff closure() # Call closure # Finish stuff
if __name__ == '__main__': lock(): # Do some things here is thread safe ```
