Good. :-)
that was a very long post that missed the actual issue. ... he just printed $!
which happens to have some value in it (and all $! values are some error
text/number!).
Agreed. I was trying to figure out a way to make readline set $!, but
ended up with a sloppy mess that, upon further inspection, fails to save
$! after calling readline.

also posting large chunks of the perldocs isn't too useful. post
appropriate snippets or refer to the docs instead.

how to fish.
* Meaning: Give a man a fish and you feed him for a day. Teach a
man to fish and you feed him for a lifetime.
2. I wanted to demonstrate my problem-solving process.
3. Putting the perldoc output into the post makes for convenient reading.
4. 100 lines of documentation isn't too bad.
5. "RTFM print, $!, and readline" is curt, and inadequate for a newbie.
6. Taking small pieces out of context can be misleading.
