Did I say that was my last post in the thread. (Hm... remember I had some little discussion with the other merlyn last time, but this merlyn is not that hot tempered one ;-)

First I never said that print was aborted, instead I said "ignored". Also I never said what being ignored is the print statement as a whole, instead, what being ignored is that $a.

Now afetr had a good sleep, I am now thinking this side tracked doscussion is meaningless (so what I am saying is that the discussion started by the thread owner is absolutely meaningful and interesting, but not this sub thread.)

Why do I say this sub-thread is meaningless? Because, in fact, there is actually no way to distinguish the differences of the two concolusions by observation from outside, i.e. any example makes conclusion 1 sounds right, would also make conclusion 2 sounds right.

Conclusion 1:

print treats undef as empty string and issues a waring.

Conclusion 2:

print ignores undef, and issues a warning.

We would realize that, those two conclusions are actually identical, if we are willing to put aside our eagerness to disapprove the other side.

merlyn, I would be more interested in discuss with you/fight against you about the strength and weakness of POE and thread, see you.
