Not under the current system design, no. Non-OOP indexed objects cannot
have named instance variables - which is why CompiledMethods are hybrid
and we are working to get rid of them. One could decide that Strings
would have the first 4 bytes as the value of a hash, but there would be
quite a few methods to change to make this work.
