Deprecated argument names

[bearophile]

I don't know much about Scala language, so I've found this small funny thing in the Lambda the Ultimate blog. In Scala parameter names can be deprecated:

def somefunction(@deprecatedName('x) y: Int) = ...

This gives deprecation warning to callers using the parameter name x.


More info. In Scala annotations are user-defined, I presume, have methods, etc.:

This helps against one of the problems Don has with named arguments.
