Missing line break at `-Yindent-colons` gives off the wrong error

[soronpo]

Minimized code

  def times(num : Int)(block : => Unit) : Unit = ()
  times(10): println("ah")

Output

Term-dependent types are experimental,
they must be enabled with a `experimental.dependent` language import or setting

Expectation

It would be cool if a line break would not be required, but if indeed it does, the error message is wrong.

[LPTK]

I don't think the error is wrong. A colon followed by code is a type ascription, and the code is treated like a type.

What would be cool is to have a way to avoid using braces and parens other than :. For instance, using @ as in:

times(10) @ println("ah")

times(10) @
  println("ah")

xs.map @ x =>
  println(x)
  x + 1

If it's right-associative (as it probably should), we could even write:

times(10) @ println @ "ah"
