One thing you have to remember though is that if you're assigning \ to a string that it does interpolate in single quotes. Eg:
# uninterpolated string
my $string = '\\\\ double escape \single escape';
# print it
print "$string\n";
# outputs - "\\ double escape \single escape"
# do your replace
$string =~ s/\\/\\\\/g;
# print it again
print "$string\n";
# output is '\\\\ double escape \\single escape'
This can sometimes be confusing, because:
$string = '\hello';
# and
$string = '\\hello';
are equivalent.
Ow, my head hurts...
