One danger with this approach is that every different application may
have its own idea of how to convert some object into an Array.

For example (1 at 3) asArray could be {1 at 3} as well as #(1 3) for some
applications, simply because there is an argument I'd like to be both
a Point or a Collection...

I see some relation with this:
