using the walrus operator gives confusing output,
i = 0
{i := i + j for j in [1, 2, 3]}
gives the expected,
{1, 3, 6}
with
print(i)
6
but when we re-run the same expression again,
{i := i + j for j in [1, 2, 3]}
gives,
{9, 12, 7}
should it not have been,
{7, 9, 12}
the value of i is correct, that is 12
running it again and again,
{i := i + j for j in [1, 2, 3]}
gives,
{18, 13, 15}
{24, 19, 21}
{25, 27, 30}
{33, 36, 31}
