support Fragments #9
Description
React and Preact both have "Fragment" components, which don't render any wrapper tags but simply delegate rendering to their children. This makes components more composable in contexts where tags have a nesting context (e.g. <li> must be a direct descendant of a <ol> or <ul>).
Unfortunately the TypeScript compiler does not support a custom pragma for React's <></> fragment syntax yet, though this is on track for release soon (see microsoft/TypeScript#38720), but we can provide a Fragment component in the meantime e.g. <Fragment><li>1</li></Fragment>.
