Proposal: `if-else` and `switch` as expressions

I was told to post this here.

The proposal is nicely formatted over here:

https://github.com/Microsoft/TypeScript/issues/10841

Please discuss and someone consider championing this change to EMCAScript.

I won't be following discussion here, because I am not familiar with this
discussion list.

You might be interested in the "do-expressions" feature in v8. I'm not sure how much it's been discussed in the committee, but it's implemented (partially) in V8, so you could experiment with that. Not sure if it does what you want in the switch case, but maybe.

You could also use babel's stage-0 preset to experiment with do-expressions.

In addition to Cait's recommendation, I'd suggest proving out the grammar
before presenting a proposal. Babel provides mechanisms for defining
experimental syntax extensions, which can then be used as evidence to
support proposal discussion.

It's very important to remember that syntax additions have an extremely
high cost-for-admission.
