I'm sorry, but did you even try it? Given how easy/fast it is to try what you're about to post, I'd highly suggest it - you seem to be very prone to confidently posting completely wrong information, which suggests to me that you need to find a new source of information. May I recommend the perl interpreter itself?

Name a platform where this works the way you say it does. I probably have access to it and will test it out. AIX (4 or 5), Sun (2.6 through 2.10), HP (11i, 11.23), HP/ia64 (11.23), Linux on ia32, ia64, amd64, ppc64, s390. Windows on ia32, ia64, or amd64 (although the latter two will take me a couple hours to get, I will call you on it). You pick. You even get to write the script if you want.
