Thank you ag0aep6g, especially for the missing shared in my

Since I'm implementing a (hopefully useful) library, it would be 
unpleasant for users to have to cast away shared to print the 
info.

It works with immutable at the condition that I declare the 
toString() method like this

     string toString() immutable {...}

There is also no missing opEqual.


Is it possible to instantiate immutable objects by using emplace 
and modify the object in the toString() call ? This is to cache 
the resulting string to avoid creating a new string at each call.

I would have to cast away the immutable attribute of 'this'. Is 
this possible ?
Note that the objects would be instantiated by emplace in a void 
array at start up. So the memory is writable.
