 Additionally, if no child element is explicitly added to a `GridElement`, but the block returns an array of strings or numbers, those will be converted to `TextElements` and added as children to the `GridElement`. For example, these are identical ways to create a grid of strings

 Similarly, if no child element is explicilty added to a `BoxElement`, but the block returns a string or number, that value will be converted to a `TextElement` and added as a child. For example, these are identical ways to create a box with string content
