I would never use half those $' $" $`... little suckers

    Where's the (official) document with all the $' $" $` etc. all
    concentrated on one line? The best I could do is
    $ perl -nwe '$h{$_}++ for /^X<(\$[^>A-Z\d]+)/;END{print "$_ " for keys %h}' /usr/share/perl/5.10.0/pod/perlvar.pod
    $& $) $% $| $] $/ $. $! $; ${^ $( $@ $= $, $a $\ $? $[ $$ $^ $` $" $~ $- $_ $: $+ $'
    Anyway, I would never use half those little suckers. You see often I use
    one liners in Makefiles, and all the escaping and Emacs font color wrong
    guessing is just not worth the excitement.

    The predefined Perl variables are described in 'perldoc perlvar'. They
    are not listed on one line, but that wouldn't be very useful.
