Fixed in f9c0400392843540a87985a67ffb9fb6e4dbc2fa. It doesn’t provide a hint though. I thought we may want to provide ‘load*’ a type predicate that it would check, so that it can say “got #<undefined>, expected <package>”. However, we’d need a contract rather than a mere predicate to have nice error reporting, so I decided to punt on this for now. Ludo’.
