title: In ActionScript Bytecode, what does NewActivation mean?
body: <p>Some methods use it some don't, obviously that's specified by needsActivation flag, nut what does it do and when to use it and when don't?</p>
  
  <p>The information on AVM docs is somewhat ungenerous:</p>
  
  <p><i>Creates a new activation object, newactivation, and pushes it onto the stack. Can only be used in methods that have the NEED_ACTIVATION flag set in their MethodInfo entry.</i></p>
