Why & & lsquo; this & rsquo; is a pointer, not a link?
Is there any reason for this in C ++ as a pointer and not a link other than a historical language solution? This seems strange given that, for example, to copy the constructor or assignment operators accept " that " as a reference, rather than a pointer.
