This is from a year ago, but this is also the first time I've heard of it. Do we know the progress of this movement today? Googling for "Dash Language" and variants doesn't give me anything of note.
So is it Dash or Dart? It was referred to as Dart earlier in the week when someon linked the conf that Lars Bak / Gilad Bracha (spelling) would be revealing all at. I'm confused now.
