I agree that encouraging people to debug their own problems is good. I disagree that encouraging a ton of people to cut'n'paste your 3 lines accomplishes that goal.

I also disagree in this specific case because I think that not obscuring an important point would be more valuable here than some trivial attempt to modify behavior.

If this had been, for example, a private e-mail reply to the question, then the weights shift and encouraging the original querist to actually try the code makes sense.

In reply to (tye)Re2: Why or why not? - local undef $/ by tye
in thread Why or why not? - local undef $/ by TGI
