Ah, so semicolons are absent by default? That seems like the right decision; making semicolons optional and yet canonicalizing their universal use almost certainly leads to contention down the road (cf Javascript).
I think there's a bit of confusion here. This isn't an automatic semicolon insertion rule like JS, Scala, or Go have. It's sort of an automatic semicolon *deletion* rule if anything. Basically, it makes the presence of a semicolon not change the block result value. You still need to use semicolons to separate statements, as always.
I'd be interested to see this happen, but I'd like to see how it works with unignorable return values. Do you have a branch that we can play with?
This doesn't implement unignorable return values. I originally thought the two issues were intertwined, but they actually aren't; the semicolon rules can be relaxed while still allowing return values to be ignored. It's a backwards-compatible change for all intents and purposes.
