• evy: Get a start on indexing issue [1]
• evy: Get a start on not set isUsed var issue [2]
• evy: Get a start on tests for weird step ranges [3]

[1]: this doesn't seem to work:

a := [ ([1 2 3]) ([4 5 6]) ]
a[0][1] = 7

Also

(a[0])[1] = 7

although that doesn't really need to work if the former does (Thanks, @camh-)

[2]: You need to set v.IsUsed when used on the left-hand side in an array index. e.g:

a := [ ([1 2 3]) ([4 5 6]) ]
b := a[0]
b[1] = 7
print a

This prints the error that b is not used, but it is. (Again: Thanks, @camh-)

[3]:

for x := range 0 (-1) 1 -> no an issue. 0+1 > -1
for x := range 0 1 (-1) -> also not an issue i think: 0 + (-1) < 1
