in reply to Surprised by split

The '\' has a special meaning in a double-quoted string. And _also_ a special meaning in a regex. You'll need two of them in order to break through both special meanings.

But the first argument to "split" should be a regex. So don't pass it a string :)

See... now I'm wondering about split qr(\|) and split m/\|/.

    Hmm: 
    $ perl -e '$a="m|b|a"; print join(",",split "\\|",$a),$/'
m,b,a
$ perl -e '$a="m|b|a"; print join(",",split /\|/,$a),$/'
m,b,a
$ perl -e '$a="m|b|a"; print join(",",split m/\|/,$a),$/'
m,b,a
$ perl -e '$a="m|b|a"; print join(",",split qr/\|/,$a),$/'    
m,b,a
$ perl -e '$a="m|b|a"; $b=qr/\|/; print join(",",split $b,$a),$/'
m,b,a
$ perl -e '$a="m|b|a"; sub b{return qr/\|/}; print join(",",split b(),
+$a),$/'
m,b,a
$ perl -e '$a="m|b|a"; print join(",",split "[|]",$a),$/'         
m,b,a

    Man, I love perl. :) (Updated a couple of times to add new variations)
