How to reference a var in an array?

[boomie]

Is there a way to store a reference to a variable inside an array?
something like:
b = 1;
a[0] = reference(b);
get_referenced_var(a[0]) += 1; //now b=2
is it possible in gm:s2?

No, GMS 2 still passes variables by value, not by reference.

That´s unfortunate... they are talking about big changes to gml, I hope they will add this option.

if the variable is also an array then it's possible
my_arr[0] = 10;
my_arr2[0] = arr;
doStuff(my_arr2);

///doStuff(arr)
var arr2 = argument0;
var arr = arr2[0];
arr[@0] = 0;

convoluted... simplified you can change array values with the @ accessor
my_arr[0] = 10;
doStuff2(my_arr);

///doStuff2(arr)
var arr = argument0;
arr[@0] = 0;
