I didn't say it did. I was just clarifying *my opinion*. When I asked
for no golfing in that thread, it was because in *my opinion* it was
off-topic for that thread. When you called me on the statement, I
thought I better clarify *my opinion*, hence I clarified while using
the pronoun "I". You can discard *my opinion* and I don't care. Don't
call me arrogant, however, for responding to a personal query with a
clarification of *my opinion*.

I never used the word wicked; please don't put words in my mouth.
Hijacking a newgroup thread is not evil, wicked or in any way morally
wrong.

Because I made a mistake. I'm glad that someone caught the mistake and
brought it to light. I have learned from it.

Because I was focusing on the difference between chomp and chomp!,
about which I was mistake anyways. If you compare that code against
Johns original example you'll find one difference in one character:
the removal of the !. I made that one change because I believed,
mistakenly, that the difference between chomp and chomp! is what was
breaking my code. After jumping to that premature and mistaken
conclusion, I didn't take the time to proof the rest of his method. I
apologize for any confusion that may have caused.

No, it wasn't. It was lazy, yes. It was a mistake, yes. But not arrogant.

Again, that was based on my incorrect assumption about chomp! always
returning nil. I made a mistake. I apologize. I was not trying to be
rude, just helpful.

I would argue point 2, but only due to personal taste. I concede points 1 and 3.

I did not dismiss your version because I thought it was golf. I
dismissed it because I thought, mistakenly, that is was incorrect. For
that I apologize.
Nor have I said golf is a Bad Thing; witness my clarification to which
you have responded.

I never said golfing was evil. I never said or implied that Matz made
a mistake by including $_. I never said or implied that $_ is not
useful. And I definitely never said or implied that my opinion
outweighs that of Matz. Please do not attribute views to me that I do
not hold.
I discouraged the use of $_ because I believe it to be less readable
than using a named variable. Indeed, John's original post asked for a
way to incorporate a variable into his solution in place of the $_.
