The correct way to say this is that the language standard doesn't define
the function.  However, most (if not all) CL implementations have a
"put" function, and go to various lengths to make it less visible.
Usually, a determined user could still get to it; but then of course
a program using the function would not be portable CL.

"Setf" is a macro in CL also.
