Hello. I would like to know if the compiler will generate move
constructors, as it does with copy constructors, because it can be
implemented as a move of each of the parts of an object.
I've realized looking at the documentation for the standard that
CopyAssignable is a refinement of MoveAssignable.
So I tried in conceptgcc not to define move constructor and it works.
Is this correct.

There was one proposal to allow the explicit addition of default move
constructors, move assignment operators, and swap functions with the =
default syntax. No proposal has been made to add these functions
implicitly, for reasons of backwards-compatibility.

As for the concepts, any object that can be assigned from a rvalue of
class type (including any with an assignment operator taking const T&,
which is declared implicitly) will meet the requirements for
MoveAssignable. By removing just the move assignment operator, you
have probably left the copy assignment operator there, fulfilling the
concept.

I hope this helps.
