Incorrect `x$1` completion in anonymous function

[jkciesluk]

Compiler version

3.2.1

Minimized code

After typing x completion x$1 shows. I wouldn’t expect it to, but the code compiles

  List((1,2), (3,4)).map {
    (ab, _) => x$1
  }

Output

It compiles

Expectation

I wouldn’t expect both to see this completion and for the code to compile.

Thank you for reporting!

Scala 2 also allows the following to compile, however x0$1 (the anonymous lambda parameter) does not appear in completions

List((1,2), (3,4)).map {
  case (ab, _) => x0$1
}
