[arturo-lang]

Thanks a lot for letting me know about the documentation website. There are some known issues but I've been putting them off until the upcoming update (which will coincide with the new release, which is coming very, very soon). Regarding parentheses vs square brackets, let me explain.

Basically, in Arturo, the two things are totally different:

- with parentheses, all you do is prioritize the evaluation of a given expression - now square brackets denote a block (of values) - one of the most basic building blocks of Arturo. And a block is not to be evaluated until we need it.

The case of `?` (which is an alias to the function `switch`) may look somewhat weird, but it follows Arturo's rules 100%. Have a look at the documentation: https://arturo-lang.io/documentation/library/core/switch/

Basically, the "normal", straightforward syntax would be:

``` a: switch 2 > 3 ["yes"]["no"] ```

Now, `-> "yes"` and `["yes"]` are exactly the same. All `->` does is wrap a single, computable value into a block (it's syntactic sugar, nothing more).

Now, why would we need parentheses in your example? (as you see, in mine, none was needed, as the order of evaluation is pretty much obvious)

if we did it without parentheses, given Arturo's right-to-left evaluation rule, it would mean something like: check if 3, if it's true, return "yes", otherwise return "no" and then compare that with 2. That's why we need the parentheses. But it's because `?` (switch alias) acts as an infix operator.
