Yes, _values is not intended for that, although it depends on how the
values are generated, of course...

We probably don't need utility functions for everything, simple
solution, not that nice, but ok when values may appear more than once:

  local expl

  compset -P '*,'
  _wanted foos expl foo compadd -qS, calculated values

More sophisticated, values may appear only once:

  local expl comps suf

  comps=(value calculation goes here)

  compset -P '*,'
  comps=( ${comps:#${~IPREFIX//,/|}} )

  if [[ $#comps -gt 1 ]]; then
    suf=(-qS,)
  else
    suf=()
  fi

  _wanted foos expl foo compadd $suf $comps

If you want to generate the matches even later, I'd suggest using the
first version with _wanted calling a utility function that builds the
matches. But if those values are the only possible matches in that
context and hence are the normal completions in that case it's
probably not worth it and the code above should be enough.
