Invocation: reshape scheme for data-access for Param-Weaving-Pattern

Browse source 
As it turns out, we need to embed the Param-Functor tuple,
but only for a single use from a »builder« component.

On the other hand, the nested »Slot« classes are deemed dangerous,
since they just seem to invite being bound into some functor, which
would create a dangling reference once the `ParamBuildSpec` is gone.

Thus it's better to do away with this reference and make those accessors
basically static, because this way they ''can'' be embedded into param-access
functors (and I'd expect precisely that to happen in real use)
