[Boost-users] [shared_ptr] commit/rolback

Wouldn't it be nice to extend shared_ptr to support transaction-like 
semantics? Or is it possible already?
Sometimes it's needed to execute code on exit only until we haven't reached 
some point (of "no return"):

{

    shared_ptr<void> cr_guard(static_cast<void*>(0), bind(rollback_fun, x, 
y));

    [...some critical part which should call rollback_fun on failure 
only...]

    //don't call rollback_fun if we get here
    cr_guard.commit();

    [...any code that follows...]

}

Thanks!

Wish you well!
