Can CoroutineCollection<T>.replaceOne(replacement, options) be made non reified?

[jfontsaballs]

I'd would like to ask why this function is reified, and whether it can be made non-reified?

kmongo/kmongo-coroutine-core/src/main/kotlin/org/litote/kmongo/coroutine/CoroutineCollection.kt

Line 1856 in a64be58

suspend inline fun <reified T : Any> CoroutineCollection<T>.replaceOne(

Concretely, maybe this line can be rewritten? If using T::class can be avoided, there's no need for the function to be reified, thus allowing it to be used in non-inline generic functions.

kmongo/kmongo-coroutine-core/src/main/kotlin/org/litote/kmongo/coroutine/CoroutineCollection.kt

Line 1859 in a64be58

): UpdateResult = replaceOneById(extractId(replacement, T::class), replacement, options)

// Possible rewrite:
replaceOneById(extractId(replacement, replacement::class), replacement, options)

The save function has, I believe, similar behavior if the involved class has an _id property, without it being reified.

kmongo/kmongo-coroutine-core/src/main/kotlin/org/litote/kmongo/coroutine/CoroutineCollection.kt

Line 1262 in a64be58

suspend fun save(clientSession: ClientSession, document: T): UpdateResult? {

My use case is as follows: we are building a internal library where we want to write a class that handles certain operations with a MongoDB database, but the concrete type can vary between different usages of the library. It is impossible to write this class using inline functions and reified generics, so we must use non-reified functions.
