import scala.annotation.static
class Foo

  @static val bar: String = "bar"

  @main def main() = println(bar)
}

@static never made it into the language spec. It's a dotc "compiler feature" for the JVM, not a language feature. Use at your own risk.

That said, PR welcome to make it work on Scala.js anyway. Expect hard problems near initialization semantics, indeed.

Could an SJS-specific miniphase (or something) just drop the annotation? Edit: I'm not trying to use it on JS, I just want my code to cross-compile 😅

Maybe, if it doesn't affect observable semantics?
