@smarter is something similar needed for dotc? In nsc, annotations that are subtypes of ConstantAnnotation (and Java annotations) are represented differently internally. |

Honestly no idea, I never got what ConstantAnnotation was for and Dotty doesn't treat it specially. |

(now that it's possible to do so, after scala#9463) In this case of e.g. `implicitNotFound`, this makes it clearer that the custom error message must be a literal value. Fixes scala#10424 Co-authored-by: Seth Tisue <seth@tisue.net>
