Compiler version

Minimized code

def f: Unit =
  
end f

Output

2 |end f

  |postfix operator `f` needs to be enabled

  |This can be achieved by adding the import clause 'import scala.language.postfixOps'
  |or by setting the compiler option -language:postfixOps.

Expectation

Should compile or should have a better error message.

It feels like it should behave the same as

def f: Unit = {

}

I ended up in this situation when I did something like this.

def f: Unit =
-  val x = ...
-  g(x)
+  // val x = ...
+  // g(x)
end f

The code was much longer.
