true continuations

Some implementations call themselves "continuations", but in fact are not.

Proper continuations generally are implemented via a spaghetti stack, and must include garbage-collecting / reference-counting.

Languages that can do multi-shot continuations:

• Felix
• Ruby 1.8, Ruby 1.9.1, Rubinius
  • note: continuations were removed in Ruby 2.0

Languages that can only do one-shot continuations:

• Lua [1] [1] [2]
