In the descriptions of <b>this</b> and <b>super</b>, this page says "Within a
non-static member function, <b>this</b> resolves to a reference to the object
that called the function." This seems to be a mistake. A function couldn't and
shouldn't have information about its caller. Plus, functions are called by
functions, not by objects.

My suggestion for a description of <b>this</b> is as follows:
Within a non-static member function, <b>this</b> resolves to a reference to the
object for which the function was called — the current object, whose members
are in the current scope. [second sentence unchanged]

And <b>super</b> could be described quite consisely:
<b>super</b> is identical to <b>this</b>, except that it is cast to
<b>this</b>'s base class. [next four sentences unchanged]
