[Seaside] Strongtalk

[Boris Popov]

If you can copy/restore the stack, you should be able to implement continuations. In Squeak and VisualWorks, you can get your hands on 'thisContext sender' which you can decompose, save then (later) load, compose, swap in place of a current stack and proceed. See class Continuation for how it does it (#initializeFromContext: and #restoreValues among others).

Hope this helps,

-Boris

"VMs do not support the stack-copying techniques
Seaside uses to implement backtracking"

I'd like to know where I can find information on these
stack-copying techniques. 
I mean, how to check if a VM does support it? there
are some key methods I should look for? 
thanks
