in reply to Duplicate variable returned from sub

It’s easy enough to test–

perl -Mstrict -wE 'my ( $v1, $v2, $v1 ) = ( 1 .. 3 ); say $v1' "my" variable $v1 masks earlier declaration in same statement at -e li +ne 1. 3

I would not rely on the behavior though. Definitely fix it by cutting out the duplicates.

    I am addressing the code issue, yes. Since we're running this on Linux and Solaris, I really don't want to rely on a "quirk" that the code run the same. Thank you!

      You could make this explicit by using:

      my (undef, $var2, $var3, $var1) = someFunction($var4);
      or refactoring someFunction() if that makes sense.

        I'm refactoring the function call. But was curious where the undef would need to be if I needed a "fast fix".
