There was a problem hiding this comment.
This expression is a bit dense. I believe the following would be slightly longer, but more readable:
val paramSymbol =
for {
DefDef(_, _, paramss, _, _) <- tpd.defPath(funSym, classTree).lastOption
param <- paramss.flatten.find(_.name == name)
} yield param.symbol
paramSymbol.getOrElse(fn.symbol)
