I'm registering a callback with some C code. The simplified story is
here, but the actual code is on GitHub [1] at the end if you care.
The call looks something like this.
void register(void(*fp)(void*), void* context);
I have a class that holds state for the callback and registers itself:

Not currently. However, std.variant.visit is probably what you
want. It enforces that you handle all types contained in the
Algebraic.

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();

You can have a mutable pointer to const data in D, too:

1) Such placement based syntax is foreign to D.
I would have to agree that this is a strange way to do things in

The great int* a vs int *a debate...
2) It would be special syntax just for class types.
IMO, it would be worth it
3) It's not how C++ rolls.

Is there a better way other than

`const Test test;` and `Test const test;` are equivalent in
C++. You need that '*' in C++, too, to make a distinction
between reference and data.
