Which is faster? I assume the first.

SpeedQuestion.cs

var near = self.World.FindActorsInCircle(self.CenterPosition, info.Range);
foreach (var actor in near)
{
	var foo = actor.TraitOrDefault<FooBar>();
	if (foo == null) return;
	// do stuff
}

var near = self.World.FindActorsInCircle(self.CenterPosition, info.Range)
	.Where(a => a.HasTrait<FooBar>());
foreach (var actor in near)
{
	var foo = actor.Trait<FooBar>();
	// do stuff
}
