Comprehensions with iteration index/key

[oridag]

I see that AST support for comprehensions that include an extra iterVar that is populated with the index (lists) or key (maps) was recently introduced in the expr proto:
googleapis/googleapis@24be099

Any guidance on if and when we can expect it in the cel-java runtime?

Support for two variable comprehensions will be added for CEL-Java in the future. This was added in cel-go recently, so we'll just need to port this over: google/cel-go#1034. We don't know when yet, but my guess is that we'll start tackling this sometime in early 2025. The feature is pretty self contained -- we wouldn't mind accepting contribution on the port if you need this much sooner.
