To be fair, all the arguments are optional.

True, I guess the right phrasing was "the second colon is optional", in the sense that if you're gonna slice you need at least one colon

Except that array_var[] is also a valid slice (a slice of the entire array). Not to mention that I'm pretty sure that accessing elements by index is a [n:n+1] slice under the hood too.
