local trigger leaking...

Ok, if I make a local trigger, should I set the variable to null, or are triggers not considered handles?

for example.

Jump through the hoops for anything which you intend to Destroy* or Remove* later.

Umm what? Does that mean null or leave it alone?

Everything that is a handle can be nullified, so if you do that, is like ensuring that your code will run without leak.

Personally, I set to null the triggers in the inittrigger function.

Ok, thats what I wanted to know. Thanks.

It is not necesary to set handles to null if they are not going to be destroyed (dead units, Destroy* or Remove* functions)

although most of times, setting them to null won't cause any harm and helps you get a nulling habit with the problem of timers though

Triggers are handles, but as vex mentioned, persisting handles don't have to be nulled, other than temporary handles.
