Oh, you're right, we have been avoiding dots in variant names. We have a lint 
check that says "use [A-Za-z0-9_]+ only". 

Using "-" in a variant name probably actually causes a problem (because it 
could get confused with the syntax for disabling a variant). However I'm not 
sure if "." is really a problem or if we were just being overly cautious and 
could relax that restriction.
