Description
Sorry if this has been discussed but it is hard to search for such a generic combination of words.
Is there any plan to implement support for https://github.com/tc39/proposal-do-expressions http://wiki.ecmascript.org/doku.php?id=strawman:do_expressions
It would be awesome to be able to avoid the extra code required when wrapping an if statement in a function to get a dynamic return value.
Thanks!

Research direction
Read the linked TC39 do-expressions proposal first to understand the requested ECMAScript semantics, then inspect TypeScript’s existing compiler support for new syntax. Done would require an agreed implementation scope plus tests covering parsing and emitted JavaScript, but this issue names no files or tests.
