I guess I don't know which is most appropriate, there are many options 
and _values seemed to fit the bill.

I pared things down for my question, but to be more exact I want 
completion for an option.  Something like:

_arguments : '--foo[Which foo to use]:foo:_values whatever 'a\:\:b' 'c\:\:d'

i.e. the --foo option has a limited number of legal values.  What would 
you suggest I use here?
