int[] a = [1,2,3]; // length == 3
fun3(a);
assert(a.length == 3); // holds.
If you have fun1 and fun2 you might have no use case for fun3.
That is however no reason to disallow fun3, especially since
there are situations where you don't won't to have fun2.
Keep in mind, that I'm only arguing against a ban of fun3 and the
notion that it's behaviour is more unpredictable then fun2
although it offers stronger guarantees.
