Extension method is not shadowed by regular method

[som-snytt]

I was surprised that the extension is not shadowed:

object Test:

  extension (i: Int) def ok(j: Int) = i+j

  def test = 42.ok(27)

  class C:
    def ok(i: Int)(j: Int) = i*j
    def c = 42.ok(27)
    def f = ok(42)(27)

@main def main() = println:
  val x = Test.C()
  (x.c, x.f)

The reference language is "available as a simple name", as in Scala 2, and def g = ok in Scala 3 means the local ok and not the extension.

Noticed at https://discord.com/channels/632150470000902164/632628489719382036/1195117929155530792 where my surprise was that braces in REPL 3 do not mean locally. As shown, the extension becomes an imported member for res1 which is not shadowed.

scala> { extension (i: Int) def ok(j: Int) = i+j ; 42.ok(27) }
def ok(i: Int)(j: Int): Int
val res0: Int = 69

scala> { def ok(i: Int)(j: Int) = i+j ; 42.ok(27) }
def ok(i: Int)(j: Int): Int
val res1: Int = 69
