Create a shared pointer that manages the same modifiable object (if any) as the specified `other` shared pointer to the (template parameter) type `COMPATIBLE_TYPE`, uses the same deleter as `other` to destroy the shared object, and refers to `(ELEMENT_TYPE*)other.get()`. If `COMPATIBLE_TYPE *` is not implicitly convertible to `ELEMENT_TYPE *`, then a compiler diagnostic will be emitted indicating the error. Note that if `other` is empty, then an empty shared pointer is created, which may still point to an un‐managed object if `other` were constructed through an aliasing constructor.
