Well, this was not exactly point of my question - how to do this. There 
are few "valid" ways - getters/setters (properties) is one of them, to 
have const pointers to mutable data is other, and perhaps there could be 
even more.

I just wanted to point if such usage of union is invalid, it will be 
nice to assert this in compile time or at least have note in specs.

Or rather I wanted to comment on using invariant and const in this 
context lead to same effect - immutable declaration, which is feels 
wrong. If I were used invariant - this would be exactly what I expect. 
But for const I hope to get readonly view of any data, be it immutable 
or not.
