Well, realize that being able to do something doesn't make it the right
thing to do in a particular situation.   I don't think Arnaud's goal
here is to show that functional programming is bad, rather he's forcing
me to work out whether or not it could be done without breaking existing
syntax (and a fine job he's doing too).   The examples we've been
working through are testing specific cases.  It doesn't mean it would be
the recommended idiom for these cases.   

When I was testing the macro feature for Breve (a bad name for the
feature, I now realize), I wrote intentionally horrific code, simply to
test that the solution was general enough:


Would I ever do that in real life?  Only for testing =)
