Hi all, ``` auto foo(const int[3] x) { int[3] y = x; y[0] = 1; // line 4 return y; } immutable int[3] a = [0,1,2]; immutable int[3] b = foo(a); // line 8 ``` compiles with an error: ``` 4: Error: cannot modify read-only constant [0, 1, 2] 8: called from here: foo(a) ```
What am I doing wrong? Thanks, Johan
