i thought i was crazy for a second there.  Then i realised that i just 
hadn't stated the problem fully. :)

for a more general solution,

$t =~ s/\\(.)/\$1/g; # was the best i could guess at

and doesn't work of course.  I'm running an Expect app with stuff drawn 
from a database, so "\r", "\n", "\whatever" is highly probable. :)
