      Don't miss it: Babel already implements do expressions, so you can put `if` inside your JSX.https://github.com/reactjs/react-future/issues/35#issuecomment-120009203 …

      @dan_abramov that’s hideous, so much harder to read than a ternary expression

      @forbeslindesay I hate nesting ternaries. Also, (cond && stuff) always felt like a hack when there's no "else" branch.

      @dan_abramov except there is an else block, it’s just implicitly `undefined`

      @forbeslindesay The idea is to have JSX expression containers have the same semantics as do expressions. @dan_abramov

      @sebmck @dan_abramov but what’s the justification for do expressions. I haven’t seen any discussion on esdiscuss

      @forbeslindesay Pretty sure it's from the ES4 era. Nicer than an IIFE. @dan_abramov

          @sebmck @dan_abramov the implicit return inside if/else etc. is very strange.

          @forbeslindesay It's reusing existing completion record semantics. Same behaviour as eval etc. Most commonly used in REPLs. @dan_abramov
