Single quotes or double quotes, I can get it to work with 'four' slashes. See below

>echo $perlcode
$a="x\\y\\z";@b=split('\\\\',$a);print join(";",@b),"\n"
>perl -e "$perlcode"
x;y;z
[download]

or

>echo $perlcode
$a="x\\y\\z";@b=split("\\\\",$a);print join(";",@b),"\n"
>perl -e "$perlcode"
x;y;z
[download]

I would have thought that if 4 back-slashes would work with double quotes (becoming \\ instead), then 2 back-slashes would work with single quotes.

Maybe some wise monk would enlighten us?
