Should filter et al. pass on this.value as this.error?

[kwisatz]

IMHO, after a filter, e.g. in a recover, recoverWhen or errorMap, it'd be useful to have the original value being passed on as this.error (without having to tap and store it in a variable of higher scope.

IDK, people usually have a clear expectation of what filter means. Nobody ever complained that Array's filter doesn't preserve the original values.

However, there might be room for an additional utility function.

I'm sorry, I don't remember the exact use case I had. I should have written the ticket right then. I'll amend this when I come across this need ever again.
