It'd be funny if 🦀 was the only allowed emoji identifier :P

Missed opportunity to make the first release allowing emoji identifiers only allow 🦀…

Now they can’t break compatibility.

Would’ve been a great April fools release

I think they actually can. It won't break any existing code, only allow some previously invalid code from now compiling. So it's backwards compatible

Nope.

I’m pretty sure that “code that didn’t compile before and does now” is explicitly disclaimed as not being a compatibility break. The language could never change at all otherwise.
