i’ve found a good alternative is returning functions

eg. you have a function like this:

def cycle(func): func=func()

then you start with cycle(main)

def main(): return intro

if __name__ == '__main__: cycle(main)

and then main returns the next function, and following functions return functions…

def intro(): if thisthing: return thisfunc if thatthing: return thatfunc

return is being used like goto
