You could simplify it like this:

class SomeRepository(
    private val memoryCache: MemoryCache,
    private val database: Database,
    private val network: FancyShmancyNetwork,
) {
 
    suspend fun fetchSomethingWithSecret(
        secret: String,
    ): Result<Something> = memoryCache.get(secret).flatRecover {
        database.get(secret).flatRecover {
            network.get(secret).onSuccess { something ->
                database.set(secret, something)
            }
        }.onSuccess { stuff ->
            memoryCache.set(secret, something)
        }
    }
}
Stop throwing exceptions!

You could simplify it like this:
```
suspend fun fetchSomethingWithSecret(
secret: String,
): Result<Something> =
withContext(Dispatchers.IO) {
cache.get(secret)
?: database.get(secret)
?: network.get(secret)
}
```
and return success or null for the cache and database cases.
