Complexity reduction for language bindings is my primary objective.
Using the current interfaces, my foreign data structures have to be
pressed into C data-structures. This is done doing a lot of heap
allocation, even for primitives. Data trees have to be traversed twice,
once for conversion and second for marshalling, the same on response.

On marshalling the data tree is traversed to marshall its leafs. Doing
demarshalling leafs and nodes have to be created. Generic tree
traversing and tree construction can be encapsulated using interfaces,
design patterns of wrapper and factory. Additional heap allocation would 
be obsolet, primitve conversion could be done in space.

Performance could be an add on in terms of

T(interface interaction)
--------------------------- < 1
T(previous heap allocation)

but this is not expected.

orbit-foreign is thought for scripting languages, NOT for C, C++,
Modula, etc.
