<< Tail calls >>

• A tail-call is when the last expression in a function is a function call.
• Desirable that tail-calls not grow stack.
• This is tricky in JVM.
• Solution is to split function call into 3 parts:
  1. Evaluate arguments and save them and called function in well-known location.
  2. Return from method compiled from current function.
  3. Call the function using an outer driver loop.
