Something that was brought up after the prior Law 12 discussion was how FIFA's Laws of the Game apply to a situation where a player hangs off the crossbar during the course of play. This player could, of course, be a goalkeeper, a defender, or even an attacking player.
So... what do we do? My immediate instinct is to blow the whistle and stop play, but why? There's nothing outright in the Laws of the Game for either soccer or futsal that directly discusses a player using the crossbar as an aid to play.
So where does that leave us?
