A modern programming language that makes developers happier.

kotlinlang

```
private fun doPostMessage(...) {
    var messageId: Long? = null
    try {
		messageId = messageRepository.insertSendingTextMessage(...)

        val apiMessage = apiClient.postMessage(...)

        messageRepository.updateSentMessageAndParents(apiMessage)

    } catch (ex: Exception) {
        if (messageId != null) messageRepository.updateMessageState(messageId, MessageState.ERROR)
        throw ex
    }
}
```

if  `messageRepository.insertSendingTextMessage(...)` fails you still crashing the app. without properly calling the `updateMessageState`

Why? I'd catch it, update the updateMessageState with ERROR and rethrow as a signal downstream it failed

if `insertSendingTextMessage` fails you won’t set the `messageId` so `updateMessageState` will be called with an uninitialised variable

oh, yea, in that case the update is skipped, since messageId will be null, its pseudo code, sorry
