This works fine in dmd 2.075:

struct A
{
    this(string a) {}
    this(string a) shared {}

    ~this() {}

    this(this T)(this) {} // you can reflect to find out if 
shared

void main()
{
    auto nonShared = A("");
    auto shared_ = shared A("");
    auto nonSharedCopy = nonShared;
    auto sharedCopy = shared_;

This look interesting: this(this T)(this) {}
What is it? Postblit?

It compiles but doesn't work for me.

this(this T)(this) {writeln("postblit"); }   // doesn't print 
anything

It's a template postblit constructor - it'd get instantiated 
differently depending on the type of the implicit `this` 
parameter and would be able to fix things up taking into account 
whether or not `this` was shared (or immutable).
