Computing and retrieving range metadata?

[fabiospampinato]

Hey 👋 I'm tweaking the range in my rangeExtractor function, and I'd like to render some of the returned indexes in a special way, problem is I'm computing which indexes to render specially inside my rangeExtract function, but I need to know this information outside of it.

I don't see a 100% safe way to do this given the current API shape, I was thinking maybe I could attach this information as a named property to the returned array of indexes, but I don't see any API for retrieving this array back.

Any idea on how I should approach this? Would it make sense for the library to provide users with a way of retrieving the "current" extracted row range, so that for example I could use the named property trick?

Thanks.
