Past labels are easy, but what about future labels?

  print(1)
  goto('MYLABEL')
  print(2)
  label('MYLABEL')
  print(3)

Or better yet...

  for x in range(10):
      for y in range(10):
          if x == 5 and y == 5:
              print(x, y)
              goto('MULTIBREAK')
  
  label('MULTIBREAK')
