BTW, for example

In handlerbars,

<select>
  {{# each optionListThatComeInPairs }}
    <option>{{ firstThingInPair }}
    <option>{{ secondThingInPair }}
  {{/ each }}
</select>

Or equivalently, in MDV

<select>
  <template iterate="optionsListThatComeInPairs">
    <option>{{ firstThingInPair }}
    <option>{{ secondThingInPair }}
  </template>
</select>
