When using a

Result

it's often useful to map an exception to another type of exception, has there any thought been given to adding something like

mapFailure

to the

Result

i.e.:

inline fun <R> Result<R>.mapFailure(transform: (exception: Throwable) -> Throwable): Result<R> {
    return when {
        isFailure -> Result.failure(transform(exceptionOrNull()!!))
        else -> this
    }
}

Usage:

Result
    .failure<String>(NullPointerException())
    .mapFailure {
        MyDomainException()
    }

I think this should be in the #stdlib channel
