+```js
+const getOrCreatePost = send(createPost(title).catch(createPost(title)))
+```
+
+You will likely need to define better helpers that makes it safer to handle
+rejections and work with promises. It is however sensible to have this basic
+behavior for the sendscript DSL and parser.
+
+### await
 
 SendScript as of `v2.4` supports functions to do basic templating. It does not
 support async functions and will throw an error when you define one.

 // Parse with custom leaf deserializer

+const parse = Parse(schema, env, leafDeserializer)
 
 const result = parse(json)
 ```
 
 The leaf wrapper format is `['leaf', serializedPayload]`, making it unambiguous
 and safe from colliding with SendScript operators.
 
+## Limitations
+
+The stubs the `references` function returns are limited in the way they can be
+used. This has to do with the fact that they are to be serialized.
+
+### Chaining APIs
+
+Currently you cannot do chaining APIs. `lib().doThis().doThat()`. It likely is
+possible to implement but will require more extensive schemas and obviously more
+code to create the AST.
+
+### Callbacks
+
+Although it is possible to mix client and server functions, it works very
+different to ordinary functions. Client functions can be used but should be seen
+as a templating tool to make sendscript programs; just like one would use
+JavaScript with react templates. `items.map(deleteItem)` would return an array
+of sendscript function calls which can be given to sendscript's parse.
+
+Client functions cannot be called by sendscript functions (as of yet) since we
+cannot serialize client functions. No work has been done to have the server send
+back intermediate values to perform client function calls or by performing
+smaller sendscript program payloads that are passed to the client. Very
+interesting stuff to look into. You can achieve this now but it looks less clean
+because you have to do `send` calls which is a bit manual.
+
+```js
+await send(updateUser(id, merge(await send(getUser(id)), { ...newValues })))
+```
+
+It might be interesting to allow configuration to create references that will
+trigger a send whenever await is called. That would remove the ability to create
+a single payload whenever using await. You can then write the above in the
+following manner.
+
+```js
+await updateUser(id, merge(await getUser(id), { ...newValues }))
+```
+
+Possible footgun is that updateUser is only performed when awaited (.then is
+called). This lazy behavior can trip users. This footgun could be resolved by
+checking if any outstanding work exists at the end of a step or the beginning of
+a new step.
+
+### Error handling
+
+Sendscript does not have builtin tools to handle errors. You can write your own
+utilities for that or use things like \[Ramda's tryCatch]\[tryCatch]. This will
+likely never be supported as JS try catch does not have a return value. It might
+make sense to wrap everything that can throw in promises which is easy to do
+with async functions.
