The @_ parameter to a subroutine gets populated at RUN TIME (or the time the subroutine gets called), with whatever is passed to it at that time.

In tHe first call, you pass @ARGV to the 'formlist' sub.
This returns an ANONYMOUS sub that is assigned to $arguments.
You call the Anonymous sub, pasisng it "Command Line", which, as you can see is received and printed just fine.

Perhaps we can explain it better if you tell us what you were expecting, and why.

In case you were unaware, you created a "closure" around @list, preserving it's value.

             I hope life isn't a big joke, because I don't get it.
