is there a more elegant way to do this? I would like to use `for iLine, line in lines inputFile`, so the sugar for `pairs`. However that doesn't seem to work with the `lines` iterator. Am I doing something wrong, or is this simply not possible?

```py
var iLine = 0
for line in lines inputFile:
    for iCell, cell in line:
        var val = false
        if cell == '#':
            val = true

        row[iCell] = val

    map[iLine] = row
    iLine += 1

```
