Why, why, why do you want such a horrid thing?
I have an function that isn't always doing what I want.
I make a reference to it, so I can print it from time to time,
and do some other things to try to see why sometimes I am getting
an unwanted result.

I can no longer debug my problem.
You are seriously proposing this?

I might start ahead of time, just for thinking of it ...

There has got to be a better way to get what you want -- or perhaps
for you to want something saner.
