Ichthyostega 252c735b7b Library: solve forwarding of child-expansion ...

For sake of completeness, since the `IterExplorer` supports building extended
search- and evaluation patterns, a tuple-zipping adapter can be expected
to handle these extended usages transparently.

While the idea is simple, making this actually happen had several ramifications
and required to introduce additional flexibility within the adaptor-framework
to cope better with those cases were some iterator must return a value, not a ref.
In the end, this could be solved with a bit of metaprogramming based on `std::common_type`

...and indeed, this is all quite nasty stuff — in hindsight, my initial intuition
to shy away from this topic was spot-on....
