Welcome to the Ithaca wiki!
- Should we have multiple returns?
- Pros: Functions can return a "primary" argument and hide away others until needed, potential opportunities for optimization (as opposed to copying lists around), more expressive power in general
- Cons: Getting more than 1 arg at a time can be a pain, complicates the definition of a bunch of stuff, handling 0-arg returns is annoying, special syntax just for returning multiple values
- Should we have call/cc (rather than just an exception system for non-local flow control)?
- Pros: Powerful and expressive
- Cons: Involves copying the entire stack in most cases (an expensive operation!)
