 @subsection Emacs Lisp forms as formulas

-It is also possible to write a formula in Emacs Lisp; this can be useful for
-string manipulation and control structures, if Calc's functionality is not
-enough.  If a formula starts with a single-quote followed by an opening
-parenthesis, then it is evaluated as a Lisp form.  The evaluation should
-return either a string or a number.  Just as with @file{calc} formulas, you
-can specify modes and a printf format after a semicolon.  With Emacs Lisp
-forms, you need to be conscious about the way field references are
-interpolated into the form.  By default, a reference will be interpolated as
-a Lisp string (in double-quotes) containing the field.  If you provide the
-@samp{N} mode switch, all referenced elements will be numbers (non-number
-fields will be zero) and interpolated as Lisp numbers, without quotes.  If
-you provide the @samp{L} flag, all fields will be interpolated literally,
-without quotes.  I.e., if you want a reference to be interpreted as a string
-by the Lisp form, enclose the reference operator itself in double-quotes,
-like @code{"$3"}.  Ranges are inserted as space-separated fields, so you can
-embed them in list or vector syntax.  Here are a few examples---note how the
