It seemed that the integration test will end up as a dull repetition
of already coded stuff, just with more ports and thus more boilerplate;
and so I reconsidered what an actually relevant integration test might encompass
- getting parameters from the invocation
- translating and wiring parameters
- which entails to adapt / partially close a processing function!
Thus — surprise — there is a new feature not yet supported by the `NodeBuilder`,
which would be very likely to be used in many real-world use cases: which is
to adapt the parameter tuple expected by the binding from the library.
Obviously we want this, since many »raw« processing functions will expose a mix
of technical and artistic parameters; and we'd like to ''close'' the technical ones.
Such a feature ''should be implementable,'' based on the already developed
technique with the »cross builder«, which implies to switch the template arguments
from within a builder expression. We already do this very thing for adapting
parameter functor, and thus the main difficulty would be to compose an
adaptor functor to the correct argument of the processing functor...
Which is... (well, it is nasty and technical, yet feasible).
