Alternatively, I could ask you to provide that value explicitly I suppose, but that'd be kind of annoying to thread around.
So locations wind up having to implement `Default` because sometimes we have to synthesize a location to represent the "start of the stream". This comes from a few spots in...
It would be nice to have feedback from the parser to the lexer, but it would require some significant planning because of how LR parsers work.
I don't remember much of the details here but I definitely think we should clean this up for 1.0. I was trying it out on a recent project and I...
Thanks for the PR, we're deferring this to get a short term patch out the door, we may consider it later.
@rfcbot reviewed This is a complex space, big thanks to @RalfJung for laying it out so clearly.
We've had some spurious errors similar to this around async functions for a while -- I have to find the citations -- is it likely that this is a duplicate?...
@Evian-Zhang That's a good question (though not I think one that needs to block progress on the RFC). That said, I think even *better* would be if we could avoid...
