I don't agree with that. Generally, a language specifies a virtual
machine and doesn't need to concern itself with things like "memory"
at all. Although langauges like C tries to, look at all the undefined
behavior you get when you make assumptions about memory layout etc.
Memory representation is just an artifact of a particular
implementation of the language for a particular architecture.
If I haven't seen further, it is by standing in the footprints of giants
