Thinking about this a bit more: isn't an "option" a variable that's actually a procedure in disguise? IOW, if I use an option plus an option_proc, am I not in fact using 2 procedures, for a net result that looks exactly the same to the user. I should write out the code to be absolutely certain, but I'm fairly sure that the option_proc would look almost exactly the way the procedure I described would look. Correct? And if so, are there actual advantages to using that more advanced approach other than that it uses a few nifty features from base? R.
