You have to deallocate only if the ownership still with the
same object. This is not the case when the object is moved.

 Take this code
 string str;
 int main ()
{
     string str( "hello" );
     ::str = move( str );
}
 With clang-cl (the MSVC-flavour of clang) the whole string-creation
and destruction is opmized away and the compiler directly checks if
::str contains any externally allocated and if not it makes a short
-string-optimized "copy" to ::str. That's nine instructions for the
whole string copy with clang-cl 17.0.3; no external call.
 

If you put everything on compiler bill, then you don't need move etc..
This create a language that is hard to trust.
