So why does "#(1 2 3) at: 1 put: 5; yourself" evaluate to "#(5 2 3)" ?

Instances of Array have fixed sizes, yes. But I would not say that makes
them readonly.

This works in Squeak too:
'Boy' at: 1 put: $T evaluates to 'Toy'

It won't work in (latest versions of) VisualWorks, where you have
immutable literal strings.

I don't think so.
