I can do:
array[new A()] = 42;
array[a1] = 23;
Both lines are valid.
But if I would access the elements later with their keys, I
can't because I have not a valid key for the element 42, only
for 23.
so my suggestion is: allow ref keys.
int[ref A] array;
array[new A()] = 42; // <-- error, new A() isn't a lvalue
array[a1] = 23; // <-- fine
What problem are you trying to solve here? When I forget to keep
the key around, I'll notice that. I don't need lvalue keys for
that.
