If I understand you wont something similar to the following:

#warning windows doublequote!

echo ECHO | perl -nle "BEGIN{print qq([@ARGV]);undef @ARGV}print" arg1
+ arg2

[arg1 arg2]
ECHO

PS Follow the the tybalt89 advice (while mine is more a trick): infact @ARGV is different from STDIN see a more detailed post Difference between piped-in and invocation arguments to a Perl script? and a similar one on SO

In the first Corion wisely point to I/O-Operators
