I've gone through quite a few moods, attitudes, reading this.  If you do,
seek help; I am a miscreant by profession.

Ranging from audacity and awe, to indignance, I have found the newsgroup on
the whole to be reasonable yet stubborn.  Expect me to take the other side
soon.  Erratic, fickle, go for it.  Jewett's idea,

-is- very Pythonic, blending in much better than mine.

Mine isn't after all but I don't see why or how.  Too bad too; it's a beaut'
as ideas go.

contrast.

You know how many cigarettes I'd get for free if I saved all my C-Note
Camelbucks?

More later, if at all.
