I just finished reading the doc on misuse of aget/aset for js objects and then stumbled on an example showing the wrong use of aget:
You can get the value at property "foo" with any of the following:
(. o -foo)
(aget o "foo")
I assume that last example is a doc bug from the past. I marked the priority as Major because it seems there is a big problem with misuse of aget and this doc error isn't helping.
