I have a few questions:

a) When is the first alpha release planned ?

b) Did you go the Coq/Agda route with dependent types (only total functions can be defined), the Haskell (once the DependentTypes extension lands) route (partial/looping functions can be used in types and may need to be evaluated at compile time, the compiler can loop, there is no associated coherent logic), or the Idris route (only total functions can be used dependently) ?

c) How extensible is the Standard AST ? (e.g. would it be possible to define something like the Coq tactic interface from within the language, or through a compiler plugin ?)
