Minimized code

//> using scala 3.8.0
def g(op: Int ?=> Boolean) = op(using 42)

def f(x: Any) =
  x match
  //case s: String if g(s.length > 4) => println(s)
  case s: String if g:
    s.length > 4
  => s
  case x => x.toString

@main def main =
  println:
    f("hello, world")

Output

8 |    s.length > 4
  |    ^
  |    indented definitions expected, identifier s found

Expectation

Scala continues its tradition of clean syntax excellence.
