Watch out for named args translations:

```
qbin/scala -Xprint:typer -nc -e '@deprecated(since = "2.11", message = "defunct") class C'
/var/folders/s2/g6fgtpk52hl8njjvx8vyzr9r0000gn/T/scalacmd5268446459595577222.scala:1: warning: Usage of named or default arguments transformed this annotation
constructor call into a block. The corresponding AnnotationInfo
will contain references to local values and default getters instead
of the actual argument trees
@deprecated(since = "2.11", message = "defunct") class C
