	Recently someone asked about getting line numbers in Emacs. ...

If you mean ``on the display'', I have (after many requests) put line
numbers into the Emacs window code.  It was surprisingly easy to do
for #85, and surprisingly harder to do for #264 (which has fancier
optimization).  This should appear at UniPress sometime in the near
future.  (What will happen after that is anyone's guess ...)

	I have two questions, as well.
	1. Is it possible to bind-to-key not just a function invocation
	   but a function invocation with argument? For example,
	   (bind-to-key "function-name first-arg" "\^C")

No.  The solution I generally use is to bind the key to a helper function
that calls the main function after getting the argument(s).

	2. Is it possible to input a variable-name from the keyboard
	   ( via get-tty-variable, most likely. ) and then use that
	   variable's value somehow?

Sure:

(defun (print-variable &v
	(setq &v (get-tty-variable ": print "))
	(message &v " => " (execute-mlisp-line &v))))

(execute-mlisp-line) is the MLisp equivalent of a real ``eval'' function.
