A quotation from the full collection:

Let’s clean it up out there, guys. Nefarious users could even ship over their own PC binaries and run them on your system, which means that if you aren’t careful, they might do something useful like forcibly upgrade you to Linux. Of course, then the perl.exe?FMH.pl travesty magically goes away, along with a whole lot of other problems. :-)
