Partial Continuations in a Concatenative Language


Look here[1] for links of the theoretical background.

First, the current implementation of `reset' and `shift' are _wrong_
-- actually doubly wrong:

* the _captured_ by `shift' is delimited.
* the _shifted expression_ is placed in a delimited context.

I'm using an interface that doesn't even have a shifted expression.

So let's fix this: the API is now:

   shift / control ( quot -- )

Where the quotation is called with the continuation on top of stack.
