[Jprogramming] Challenge 7 March Bad Mess

[Raul Miller]

Unfortunately, I do not have any such scripts.

If they mattered to me, I have fixed them so long ago that I do not
remember the event.

Perhaps it matters that I view programming as an activity rather like
inhaling.  Inhaling is an important part of breathing, but if you
never exhale you will not do so well.

Put differently, I think there is an activity related to programming
which involves discarding code that's not useful.  Code is easy to
generate...

Finally, one of the things I most value about J is that it's concise
enough that I can do useful transformations on bodies of code with
relatively low amounts of keyboarding.  I can think of all sorts of
automated transforms, but ultimately it's my understanding that's the
valuable thing for me.
