Cause then they can't be accessed in the separate NASM module that we're writing

I meant that the two strings in the test runner are static, so only available to that compilation unit.

Are the two strings supposed to be static? Cause then they can't be accessed in the separate NASM module that we're writing as far as I can tell

Just got point = [-6015, 3783] and vector = [[-1639, 9654], [-1263, 4157]] as a random test case. Seems pretty obvious that the point is left of the line segment. This graph makes that evident. Am I misinterpretting the question? The way I see it, it's asking if the point is left/right/on the line if the given line segment were extended infinitely in both directions.

'9.99hm' should equal '999m'

Why would '999m' be prefered over '9.99hm'?

I feel like this would be even more interesting if it could flatten nested lists. For example:

flatten([[1, 2, [3, 4, [5, 6, 7, [8]], 9]]]) --> [1, 2, 3, 4, 5, 6, 7, 8, 9]

I feel like this should be able to be accomplished using reduce and recursion somehow, but I can't think of how without typechecking :/

+1 for a cool name :P
