Cannot annotate constructor with @varargs

[scabug]

You can have varargs constructors in both Scala and Java, but you can't annotate a varargs constructor in Scala with @VarArgs - you get an error message "A constructor cannot be annotated with a @varargs annotation".

I think this simply wasn't implemented. Original issue: #3621
Alex, do you remember perhaps?

Yes, this was not implemented deliberately. There was some problem with duplicating constructor methods, IIRC.

Perhaps it's worth taking another look.

That would be great. It would enable some nicer APIs that I currently have to resort to using Java for.

We'll be glad to support contributions, but otherwise this is not on our 2.12 roadmap (to be published soon).
