How to iterate through an array/list?

Hello, I'm coming from Java to Mojo.
It seems there is no support for iterating with "for" through a list - at least in the present version of Mojo. Here's the code:

def createFreeformExtrusion(lines:((Int,Int),(Int,Int),Optional[(Int,Int)])[], height)->String: # currently without curves.
    code=""
    for line in lines:
        if line[2]:

def createFreeformExtrusion(lines:((Int,Int),(Int,Int),Optional[(Int,Int)])[], height)->String: # currently without curves.
    code=""
    for line in lines:
        if line[2]:

Should work, doesn't it? It does work in Python.
Thanks.

lines looks like Tuple, not like List. Why not List((Int, Int),...) ?

Throws an error.

it's strange to me as well

Tuples are still a little rough around the edges last time I checked. You also can't use a list here unless you also use a variant since lists must be of a single type. I'd probably just make a simple struct since the type is quite large and unwieldy looking.
