in thread system & shell metacharacters

I'm with you. I'd use something like 
open BAR, '|bar.pl' || die qq(Useful msg: $!);
print BAR $xmldata;

and let bar.pl read from STDIN. No shell at all. OP might want a glance at perlipc.

    open BAR, '|bar.pl' || die qq(Useful msg: $!);

    ... is wrong, because it is interpreted as:

    open BAR, ('|bar.pl' || die qq(Useful msg: $!));

    ... so remember to use "or die" rather than "|| die".

        Using || die is fine as long as parens are used. 
        open(FOO, $file) || die "Couldn't open $file - $!\n";

        When no parens are present, you should use or die instead.

        Personally, I always use parens everywhere so my code is littered with || dies.
