 This is done in varReplace() in parser.py ... which just does a
literal \w+ ... I'd thought about extending it before, to allow
$(foo)s or ${foo}s or something, but it's very rarely needed not asked
for by anyone and not super trivial, so it never got done.

 One other thing you can do (RHEL-6+ yum) is:

echo 6s > /etc/yum/vars/releasevers
echo 6w > /etc/yum/vars/releaseverw

...and use those, but I'm not sure if that's better or worse from your
POV.
