Yes, I came to the same conclusion when adopting memcached. See my bug report
in the CPAN RT system[1]. The fix indeed is to remove the backslashes.

By the way, I'm still suffering from the occasional segfault in long-running
programs, when one memcached instance goes offline. Must be something in the
socket handling, but I haven't had time yet to investigate.
