Description
Compiler version
Breaks since 3.4.0 up to 3.6.4-RC1-bin-20241120-bd07317-NIGHTLY with java.lang.AssertionError: assertion failed. 3.3.0 breaks for another reason, which I didn't investigated further.
Minimized code
Command to reproduce: scala-cli doc *.scala -o scala-doc --server=false in a folder with the two scala files below.
TestBuilder.scala:
import scala.quoted._
object TestBuilder:
// transparent is needed
transparent inline def apply(inline expr: Unit): Any =
${ TestBuilder.processTests('expr) }
def processTests(using Quotes)(body: Expr[Unit]): Expr[Any] =
import quotes.reflect._
body.asTerm match {
case Inlined(_, _, bindings) =>
'{ ${bindings.asExpr}; () } // can also be List(${bindings})
}breaks.scala:
object breaks {
TestBuilder:
import List.empty
