Re^2: using multiple conditionals in a while(test)

gets translated into while( defined( local $_ = COND ) ) {.

Not quite. The $_ variable is NOT localized in a while loop:

$ echo "one           
two           
three      
four       
five       
six        
seven            
eight       
nine        
ten" | perl -e'
while ( <> ) {
    last if /seven/;
    }            
print "$.: $_\n";
'
7: seven

You're right. `C:\test>perl -MO=Deparse -e"while( <> ) { print }" while (defined($_ = <ARGV>)) { print $_; } -e syntax OK` [download] But if you're doing it yourself, it's as well to. Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice.	[reply] [d/l]

I see. I had a feeling it was a special case. Excellent explanations and examples. Thank you.	[reply]
