SPOILER ALERT!

From my understanding, the existing @_ will be passed by default when you use &subroutine instead. Is there a change in 5.6?

    You are correct that @_ will be passed to a subroutine if you call it without using the parenthesis. This is true of both 5.6 and 5.005 at least.

    However the result of the attempted assignment of a list to $_ differ depending on Perl version, and this DOES affect the output you will see.

      Perl never attempts to assign a list to $_. Ever.

      Understanding is demonstrated when correct phrasing is used. {grin}
