        <pre>This deprecation is enshrined in the C++11 standard:

" If the class deﬁnition declares a move constructor or move assignment

operator, the implicitly declared copy

assignment operator is deﬁned as deleted; otherwise, it is deﬁned as defaulted

(8.4). The latter case is

deprecated if the class has a user-declared copy constructor or a user-declared

destructor."

So "= default" doesn't help here.

Note that this is even more problematic in the face of move operations -

defining an implicit move op as explicitly defaulted will disable (define as

deleted, as seen in the above wording) copy operations.

Providing implicit ops explicitly with = default isn't a noop and should be

avoided.</pre>
