List Comprehensions: undefined existing list

[psytrx]

I wonder why this isn't reported yet, maybe I'm missing something?

var lst = [0, 1, 2];
var lst2 = [n*n for n in lst];

I expect lst2 to equal [0, 1, 4], but compilation fails with

line 2   col 26  undefined lst
    var lst2 = [n*2 for n in lst]; 
                             ^^^

The example from http://spiderlang.org/#list-comprehensions also fails to compile

main.spider

var list = [1, 2, 3, 5, 6, 7];
var doubles = [x * 2 for x in list];

Output:

main.spider
  line 2   col 31  undefined list
      var doubles = [x * 2 for x in list]; 
                                    ^^^^
