I'll keep that in mind. But there are places where a safe pipe is unavoidable
(filenames. No amount of careful quoting will save you).

Huh?

Because you never know what did the next interpreter took for unquoting:
$SHELL, /bin/sh cmd /c, or something else.

And that stupid activestate thing actually doesn't use any. Just tried:

  perl -e '$,=" ";open(F, "sleep 1000 ; # @ARGV |") and print <F>'

It passed the whole string "1000 ; # @ARGV" to sleep from $PATH.
It failed to sleep at all, of course. The same code works perfectly on
almost any UNIX system.
