Fixes List Bug and Change the way list is printed in console

[Thecarisma]

Description

This PR fixes some hidden and unresolved list error and include the addition and elevation of a new syntax in a for...loop to iterate over the list items rather than the index.

New Feature for..in

The new kind of for loop allows to iterate over the items in a list rather than the index e.g

list = ["one", "two", "three"]
for x in list {
    @x
}

Output :

one
two
three

it allows iterating over a list faster than using the index list[index] in a for loop

List printing

prior to this PR the list are printed into the console in an unordered manner which make it difficult to visually review the list. The following list is printed in below manner before and after this PR

list = [["a", "b", "c"], "ade", 2, 3, 4, 5, 6, 7, 8, 9]

Before :

a
b
c

ade
2
3
4
5
6
7
8
9

Now

[["a", "b", "c"], "ade", 2, 3, 4, 5, 6, 7, 8, 9]

If there's anything I've been waiting for, is this new style of displaying list values. Nice, we also have an improved for..in for looping lists... 🎉
