Since we have had a positive sighting of Eugene whittling at the
RC4 solution, I doubt that it is possible. ;-)
I had visions of reliving Eugene's celebrated reverse in Santa's
game by using the $\ variable, but I can't get it below 48.
It would be a winner were it not for the newline requirement.
Since variety is the spice of life, I present 5 permutations
of Spiff's solution using various special variables. If there
happened to be a Perl built-in array with value ("","\n"), the
last one would be 45.
spiff 46:
map$.=36*$.-55+/\d/*7+ord,pop=~/./g;print$..$/
46:
map$,=36*$,-55+/\d/*7+ord,pop=~/./g;print"",$/
41 (but, alas, not new-line terminated):
map$\=36*$\-55+/\d/*7+ord,pop=~/./g;print
48:
map$\=36*$\-55+/\d/*7+ord,pop=~/./g;$\.=$/;print
56:
@a=("",$/);map$"=36*$"-55+/\d/*7+ord,pop=~/./g;print"@a"
