shared_ptr already provides delayed construction, I don't see why you would want to use optional here? Because you want to store the memory in static memory maybe? For that, just use boost::aligned_storage and placement new, works with shared_ptr like the rest just fine.
sorry..i'll respond only to this last point (for the sake of a clearer discussion) because it actually contains the main issue (my code 'wish')... ...yes :) aligned_storage and placement new (plus the few additional workarounds for 'quirky' cases) are exactly/all i want...but because it is a relatively often used idiom i would like not to have to write it all manually every time...but rather have small class that wraps it up and allows me to call construct() and destruct() (with boost::in_place support and even the 'bool' left in debug builds for asserting correct usage)... -- "That men do not learn very much from the lessons of history is the most important of all the lessons of history."
