Scala & Kotlin annotations to store information which isn't used by Java

[Matthew Farwell]

Just a slight clarification,

You said on the latest podcast (http://illegalargument.com/episode-144-everything-sucks) that Kotlin stores extra information in an annotation.

I'm not sure whether you meant class file attribute, but Scala does something very similar, because it needs extra information as well, notably for type signatures.

See How does Scala know the difference between “def foo” and “def foo()”? and Where does Scala store information that cannot be represented in Java?

Of course, it will go even further with TASTY & DOTTY.

Cordialement,

Matthew Farwell.
