transparent inline unapply method macros are executed twice

[jchyb]

Compiler version

3.3.1, 3.4.0-RC1-bin-20240103-94e960d-NIGHTLY

Minimized code

Main.scala

@main def main() =
  val Unapplier(result) = Some(5)

Macro.scala

import scala.quoted._

object Unapplier:
  transparent inline def unapply(arg: Any): Option[Int] = ${unapplyImpl('arg)}

  def unapplyImpl(using Quotes)(argExpr: Expr[Any]): Expr[Option[Int]] =
    println("a method so nice I'll run it twice")
    '{Some(1)}

Output

compilation output:

a method so nice I'll run it twice
a method so nice I'll run it twice

Expectation

The method should be executed only one time per call, like when using non-transparent inline unapply, or when using transparent inline macros on non-unapply methods.
