And do you agree it's reasonable to expect this of every compiler?
I think that is the point of declared types. But, something like
no strong_type_check :rw
in scope can

What is the point of be able to mark things readonly if the compiler
does reject assignment attempts?

There are many possible reasons, I think.
* The code that declares the variable readonly might not be available
to you (compiled to bytecode, fetched by RCP etc),

Overloading final was Java's rather inept attempt to define objects with value semantics rather than container semantics
Can you tell me more about that, or point to something?
