Denis' original example works since 2.068.0
(https://github.com/dlang/dmd/pull/4845), so I think it would be better to open
a new bug for that.

Raising this to major because not being able to define a shared postblit kills
shared completely for user defined types.

I stumbled over this today. What I don't understand is why/how postblit can be
const? I mean if the object is const then I shouldn't be allowed to change it.
Because you are copying to something that is const.

Partial workaround:

For const/immutable postblit/dtor:
---
struct S
{
private void myPostblit() { }
this(this) inout
{ (cast(S*) &this).myPostblit(); }

private void myDtor() { }
~this() inout // Plese `inout` before `~this()` if Issue 8953 unfixed
{ (cast(S*) &this).myDtor(); }
}

struct S_ { const S sc; immutable S si; }
---
Note: at least `this(this) inout { }` or `opAssign` is required for dtor

For shared dtor:
---
struct S
{
void opAssign(shared S s) shared { this = s; } // required for dtor

private void myDtor() { }
shared~this()  // Plese `inout` before `~this()` if Issue 8953 unfixed
{ (cast(S*) &this).myDtor(); }
}

struct S_ { shared S sc; }
---

Same for constructor except it doesn't require somebody like dtor.
