At my heart, I am something like the goto instruction; my creation
sets the label, and my methods do the jump. However, this is a really
powerful kind of goto instruction. If your hair is turning green at
this point, don't worry as you will probably only deal with users
of continuations, rather than with the concept itself.
Pass a continuation to the one-argument block, aBlock and return the
result of evaluating it.
escapeDo: aBlock
Pass a continuation to the one-argument block, knowing that aBlock
does not fall off (either because it includes a method return, or
because it yields control to another continuation). If it does,
an exception will be signalled and the current process terminated.
1.40.2 Continuation: invocation
callCC
Activate the original continuation, passing back in turn a continuation
for the caller. The called continuation becomes unusable, and
any attempt to reactivate it will cause an exception. This is not
a limitation, in general, because this method is used to replace a
continuation with another (see the implementation of the Generator class).
oneShotValue
Return nil to the original continuation, which becomes unusable.
Attempting to reactivate it will cause an exception. This is an
optimization over #value.
oneShotValue: v
Return anObject to the original continuation, which becomes unusable.
Attempting to reactivate it will cause an exception. This is an
optimization over #value:.
value
Return nil to the original continuation, copying the stack to allow
another activation.
value: anObject
Return anObject to the original continuation, copying the stack to allow
another activation.
valueWithArguments: aCollection
Return the sole element of aCollection to the original continuation
(or nil if aCollection is empty), copying the stack to allow
another activation
