@enru Will need to be rebased. Conflicts with the merge of your other PR |

I would turn the phrasing around and say that retrun must be inside a method definition.

I kept the wording from the original, which is the same in scalac.

Can your rebase on top of master. Also you can now define the message as follow: case class ReturnOutsideMethodDefinition(owner: Symbol)(implicit ctx: Context)
extends Message(ReturnOutsideMethodDefinitionID) {
val kind = "Syntax"
val msg = hl"${"return"} outside method definition"
val explanation =
hl"""You used ${"return"} in ${owner.show}".
|${"return"} is a keyword and may only be used within method declarations.
