sixten

I can't answer this well and don't know of any resources, but I have seen it before in the parser for sixten: https://github.com/ollef/sixten/blob/60d46eee20abd62599badea85774a9365c81af45/src/… In that case, they're parsing a haskell-like language and can use indentation as a guide for how far to skip ahead. In a C-like language, I'd imagine you'd use braces or semicolons to see how far to skip ahead - the error bubbles up to a parser that knows how to recover, like say a statement or function body, it scans ahead to where it thinks its node ends and returns an error node, allowing the parent to continue.
