Yes, I just realised that in the sentence 'read only view' in fact the 
most important part is the 'view', and read only is not fully true so 
it's a view: if everyone's only looking at something, of course this 
thing won't change but if someone modifies it, everyone will see the change.

Agreed.

I'd say that here both enum and const could be interesting:
-const for 'traditional enum' and
-enum for 'named' enumerated objects which you could print the name..
It has always shocked me that with C/C++ (and currently D)'s enum you 
refer inside the program to an enum by it's label but outside you can't 
unless the developer makes the effort of maintaining a map (value -> 
'value string'), or then you have some documentation which must be 
maintained too :-(

But this would have the downside of surprising C, D1 developers so 
'named enum' -> label or something similar.
