Issue #8365 has been updated by matz (Yukihiro Matsumoto).

Status changed from Open to Feedback

I am sorry I don't understand the proposal, nothing more than vague idea.
Proposals should be concrete and be able to implement.

Could you describe both the model and the syntax for the proposal?

Matz.

While refactoring a wiki article about Ruby, I found this anonymous proposal:

"How about making variables objects. And assignment is the default message you send to the variable object (not the underlying reference). anintvar 5, now the variable "anintvar" is a reference to the constant integer 5. And since variables are objects, you can do some neat things like subclass variables. It would be a mixed world of static variable typing and dynamic. Use the appropriate one for a given scenario. You could also do linear casting. exm. 
                        integer new anintvar 5
                        char new acharvar anintvar

Variable types and the reference object they point to can be 2 different types. But the variable decides how to do the casting not the object referenced. "anintvar" and "acharvar" reference the same object."

I am pasting this anonymous proposal here in original full length, before I rewrite it to a more concise form in that wiki page.
