Mutable foreach list?by zigdon (Deacon)
|on Jan 11, 2007 at 15:19 UTC||Need Help??|
zigdon has asked for the wisdom of the Perl Monks concerning the following question:
I was talking to a friend about foreach aliasing the loop variable one by one through the list provided... As he was playing around with it, came across this:
And I say huh? I follow until output line "7:". I can even see why it would run 3 more times (since the list fed to foreach was evaluated before @body was modified).
What I don't get is how the next 3 elements of @headers get in there? Is this part of the "don't mess with the loop vars while looping" clause?
What am I missing?
