When broadcasting a compileFinal'ed variable using publicVariable or its variants, the variable also becomes final on the other client(s) and/or the server. Also, compileFinal does not prevent event handlers from being removed or overwritten.

in Arma 3 v1.70.141838, compileFinal also works for profileNamespace and uiNamespace. But be careful with that.

Change with Arma 3 patch 2.00, compileFinal is now unable to store code type variables in profileNamespace!
