Feature Request: Reposition Execution

[Skybuck Flying]

Hello,

Sometimes it can be handy to "interrupt/reset/reposition" a running script.

For example something externally goes badly wrong.

The script is unaware of this.

Current solution would require to have an "Abort" boolean everywhere.

The abort boolean could then be set to True to indicate all code and all 
loops must abort.

This is far from the ideal solution.

I think a much better solution could be to "reposition" the "instruction 
pointer" so to speak.

However for x86 stack clean up would be necessary. I would assume python has 
a stack too... which would need cleaning up.

Perhaps the entire stack can simply be cleaned up.

So that the point for execution continuation is always "clean".... in a 
"clean state".

So this allows for the stack to be cleaned completely... without any 
trouble.

I also hope this feature gets implemented quickly cause I kinda need it.

Therefore I will give some example code to see how it could look like:

def MyFunction():

  while SomeCondition:
     RunMyCode

return

def OtherFunction():
  while BatmanIsAliveLOL:
     BustPenguins
  return

def DetectProblem:

  if ProblemDetected:
    Aborted = True
    Abort( AbortToPoint )
  return

SpawnThread( DetectProblem)

while MyMainLoop:


   AbortToPoint:
     if Aborted:
        Reset stuff

   MainCode, Call Routines.


Bye,
  Skybuck.
