Grid only takes a single child

[abovethewater]

I imagine this is a 'works as expected' issue, but currently I cannot declare a single Grid element containing multiple Rows.

This can be worked around easily enough by enclosing Rows in a div, but that's ugly.

Should I be able to?

The following error:

Warning: Failed prop type: Invalid prop `children` of type `array` supplied to `Grid`, expected a single ReactElement.
in Grid (created by App)
in App (created by TheApp)

results from the below code:

<Grid>
  <Row is='center'>
    <Cell is='1'>
      <div></div>
    </Cell>
  </Row>
  <Row is='center'>
    <Cell is='1'>
      <div></div>
    </Cell>
  </Row>
</Grid>
