    cleaned-up flags to stop confusing myself
    
    SetLevels now uses strictess information to determine if arguments
    will become closures, this enables the -8% in cichelli and helps a bit
    in anna too
    
    I think the captors-interpretation plan is very nearly precise except
    for LNEs now
    
    I added the late-float-retry flag, it enables a rough draft in
    SetLevels that attempts to unpin vacuous cycles involving closure
    growth and fast call preservation
