It caused too many problems. I left only specialiation for scalar types.
I will need to devise clever type traits for reconizing trivial types with working constructor.

* On newer compilers `optional` is now trivially-copyable for trivial `T`s. This uses a different storage (just `T` rather than `aligned_storage`). We require the compiler to support defaulted functions and type traits. Otherwise, we still use the the plain storage for scalar types.
