The shell is evaluating "$ARGV", which comes out as an empty string. Effectively, it is just like running the following:

$ perl -e "print [1];" ONE- TWO-
ARRAY(0x7fd5ea803ed0)$

As toolic pointed out, one way to prevent the shell from evaluating $ARGV is by using single quotes around your command.

tiny update: cleaned up the prompt, in order to simplify my example.
