Well, we're not at all convinced yet. I guess your opinion on the 
subject would help us.

The reason why we first looked at a script language was we wanted a way 
to have different approaches for programming an 
event-based/function-based system. Aside from the dataflow, we would 
like to be able to change the control flow. We're thinking about having 
a timeline and a FSM framework, both with their separate GUI. So I guess 
the first idea was: let's consider rebuilding the whole core in Scheme, 
so as to allow users to use the filters the way they want.

But I guess we all start to see the limitations and implications of that 
approach. But if the core is programmed in C++ anyway, why the need for 
a scripting layer?
