How it works? Do you need some language-engine specific configuration to be
saved into the STContext in a special way (different to context's variables)?
If yes, would it be thread safe - when two threads will be acessing the same
(parent)context?

Btw. how it is with bridging Objective-C objects with io? Is it only isolated io
computation engine or can I pass objects in and out?

Is it possible to implement STEngine createMethod:... for the io language?

What error are you getting?
