Shixiong Zhu commented on SPARK-14146:
--------------------------------------
Another failure case:
{code}
scala> val x = Seq("a").toDS()
x: org.apache.spark.sql.Dataset[String] = [value: string]
scala> :paste
// Entering paste mode (ctrl-D to finish)
class Bar(s: String) {
val x = Seq("a").toDS()
}
// Exiting paste mode, now interpreting.
<console>:12: error: value toDS is not a member of Seq[String]
val x = Seq("a").toDS()
^
{code}
I created another Scala issue for this one:

> Imported implicits can't be found in Spark REPL in some cases
> -------------------------------------------------------------
>
> Key: SPARK-14146
> URL: https://issues.apache.org/jira/browse/SPARK-14146
> Project: Spark
> Issue Type: Bug
> Components: Spark Core, SQL
> Affects Versions: 2.0.0
> Reporter: Wenchen Fan
>
> {code}
> class I(i: Int) {
> def double: Int = i * 2
> }
> class Context {
> implicit def toI(i: Int): I = new I(i)
> }
> val c = new Context
> import c._
> // OK
> 1.double
> // Fail
> class A; 1.double
> {code}
> The above code snippets can work in Scala REPL however.
> This will affect our Dataset functionality, for example:
> {code}
> class A; Seq(1 -> "a").toDS() // fail
> {code}
> or in paste mode:
> {code}
> :paste
> class A
> Seq(1 -> "a").toDS() // fail
> {code}
