> have it work automatically on native Java arrays
Correct me if I'm wrong, but he is not operating on native Java arrays at all.
He redefines Array, redefines Seq and redefines WrappedArray as a subtype of Seq. He adds ident to Seq, and since Array isn't a subtype of Seq, ident is not a member of Array ( he points that out too, and provides a solution as well.
He is operating in his own "tiny parallel universe" as he says in the post. He even redefines String and CharSequence (which threw me off because isn't java.lang.String & java.lang.CharSequence already in the namespace so the conflicts etc...) Then he wants a Seq[Char] ( not the scala Seq but his redefined Seq ) to mimic the redefined String! The whole thing is quite crazy & terribly fascinating imo.
