perhaps something like Rebindable could be used.
Looking at Rebindable now, there is a useful example. There
should probably be a mention of this on the const/immutable docs.
For people coming from C++, this will not be obvious.
auto a = Rebindable!(const Widget)(new Widget);
a.y(); // fine
a.x = 5; // error! can't modify const a
a = new Widget; // fine
Given the above example though, I have to say it's ridiculously
verbose and I much prefer the C++ way. I have never used
read-only-const in C++, nor would I, and it's really annoying
that it's forced on D programmers. I can see the benefit of
protecting the underlaying data, but not the pointer/reference
itself.
I'm assuming a DIP for this would be futile at best =/
Thanks
