Isn't `trim` being applied to `Array[String]`?
I think this should be `.split(',').map(_.trim)`
```scala
scala> "A, B, C".split(",").trim
<console>:8: error: value trim is not a member of Array[String]
"A, B, C".split(",").trim
^
```
```scala
scala> "A, B, C".split(",").map(_.trim)
res2: Array[String] = Array(A, B, C)
```
