NG major features needed

This is a list of “big things” that we need to make work in the Rakudo ng branch (soon to become master):

To Do:

• slices (Pm)
• whatever indices
• grammars (Pm)
• correct parameterized Role bug (closure clone) (jnthn)
• convert Any to Cool where appropriate

Done:

• list assignment, done (Pm)
• refactor signature variable declarations, done (jnthn)
• initialize declarations to correct type object (my XYZ $foo), done (jnthn)
• hash assignment, done (jnthn)
• Range, done (colomon)
• &block.count and &block.arity are horribly expensive (and shouldn’t be), done (jnthn)
