The preserved word "as" is used in import as and is explained in the docs. I can't seem to find its use in anObject as aClass. And it is not the simplest word to search for. Am I missing something?

You can use import net.wifi as mywifi to make the wifi.open available as mywifi.open. The default prefix is the last segment of the imported path (unless the path starts with .).(edited)

That is exlained in the docs. But I meant the "as" that seems to do some sort of type casting. I saw you added this in your "services" post :

Oh. Yeah. I completely misread your question :🙂:

as is similar to is, but it casts and generates a runtime error if the given object does not implement the given interface.

So you get a runtime check (unless we can optimize it away).

OK, I hadn't expected this explanation in the topic on operator precedence.
