§5.2.(c) Multiple and mixed activations

• If activate() is invoked on a team instance that has been explicitly activated before, this statement has no effect at all (note the difference in §5.3.(a) below).
  The same applies to deactivating an inactive team.
• If a team was already active when entering a within block, it will remain active after leaving the block.
• If the team was active on entry of a within block and if deactivate() is invoked on the same team instance from within the within block, leaving the block will re-activate the team.
