# assign some chars to $_

#
# do a regexp in a regexp
#

s!^\$(.+)=(.)(\S+)(\2)$!($foo=($foo=$1))=~s,((?:n|c|u|y).), $1,g!ex;

#
# simplified:
# $foo = 'wHFG nABGURE cREY uNPXRE NAQ yNEEL';
# $3 = 'larry';
#

#
# split up "larry" into @x

# map the values 4,17,-9,-4 and -5
#

map{

#
# this can be simplified to:
#
# $y=0;
# for $a((4,17,-9,-4,-5)){
#    $x[$y] = chr(ord($x[$y])+$a);
#    $y++;
# }

# which can be further simplified to:
#
# $x[0] = chr(ord($x[0]) + 4);
# $x[1] = chr(ord($x[2]) + 17);
# $x[2] = chr(ord($x[3]) - 9);

# assign the array in @x to $print

#
# $print now holds the string 'print'
# (which was tranformed from 'larry' by the map)
#

#
# do a tranliteration on $foo to change it to
# "Just Another Perl Hacker and Larry"
