As discussed offline, one option is to create implicit def for all data types:

```

// use generics, below is for illustration only

implicit def StringToSomeString(x: String): Option[String] =

{ Some(x) }

implicit def SomeStringToString(x: Option[String]): String =

{ x.get }

```

> Currently, the usage of some in api.<function_name> is pretty awful, users have to do Some(Symbol) and then .get to use the arithmetic method and then wrapped up using another Some() to make it pass to the next layer. We should figure out a way to simplify the process.
