Import resolution problem

[dant3]

Here is an example code that makes importing scala._ stuff impossible:

object importing_issue {
  object scala {
    def evilThing = ???
  }
}

import scala.concurrent.duration._
import importing_issue._
println("foo")

which results in:

Compilation Failed
Main.scala:49: value concurrent is not a member of object cmd1.importing_issue.scala
import scala.concurrent.duration.{
             ^
Main.scala:93: value None is not a member of object cmd1.importing_issue.scala
              .print(res3, res3, "res3", scala.None)
                                               ^

and makes your repl useless.

This is tricky; we could probably make it work by maintaining the previousImports map as ordered by insertion. We'd also need to keep multiple imports from the same namespace separate rather than collapsing them into the same import statement, to support cases like

import scala.concurrent
object import_issue{
  object scala{
    def evilThing = ???
  }
}
import importing_issue._
import scala.evilThing

Which will take some elbow-grease, but doesn't seem in-principle difficult
