Here's another reason why that answer is more than a little trite. Every conditional within an if/elsif/else cascade is reported as being on the same line:

C:\test>perl sub iter{ warn join '|', caller; return int rand 3 } for(1 .. 10) { if( iter() == 0 ) { print 'first'; } elsif( iter() == 1 ) { print 'second'; } else { print 'third'; } } ^Z main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. main|-|3 at - line 1. thirdthirdthirdthirdfirstthirdsecondthirdfirstthird

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.
"Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."
