There was a problem hiding this comment.
It's hard to figure out if this is good enough because it's hard to know which trees are valid here. I think it'd be much clearer if we combined this logic and the checks from checkIfValidStaticCall in the same traversal, so we'd know exactly which tree shape we need to handle.
By the way, checkIfValidStaticCall is flawed because of local imports:
object Inline extends Macro {
val x: Macro = ???
import x._
inline def callMacro(): Int =
${ impl() }
}
The symbols of trees do not have enough information to determine the full dependencies. For example, if we have an `Ident` we need to look at its type to figure out which is the `this` prefix on which it is defined. Fix scala#18434
