Python-like iterators (pythonic)

The pythonic library provides Python-like functions for iterating over arrays. Available functions are: range(), enumerate(), items(), zip(), and zipLongest().

Example:

Draw a five by five grid of incrementing numbers:

let positions = xy_grid(5, 50)
const cnv = Canvas()
for (const [i, [x, y]] of enumerate(positions)) {
    cnv.text({text: i, x: x, y: y})
}
cnv.show()
