8.1 Symbol Components of the Elisp reference says:

The "value cell" holds the current value of the symbol as a
     variable.  When a symbol is used as a form, the value of the
     form is the contents of the symbol's value cell.  See
     `symbol-value' in *Note Accessing Variables::.

It also says:

  The value cell holds the symbol's value as a variable (*note
  Variables::).  That is what you get if you evaluate the symbol as
  a Lisp expression (*note Evaluation::).

With no statements anywhere to the contrary, these statements imply
that any use of the term *variable* is a reference to a symbol's
value cell.

By implying or outright claiming that let has no effect on the
print-name, function, or plist cells of the symbol passed to let the
manual creates a hazard that someone like me is almost certain to
fall into. (As I did.)  Nothing warned me of the danger that the
symbol made available under let is not a normal symbol and use
of functions such as fset and put have undefined results (which
I showed in my examples).
