...still fighting to find a suitable API to define how inputs and outputs are connected and mapped to function parameters. The solution drafted here uses the reshaped `DataBuilder` (≙`lib::SeveralBuilder`) to add up connections for each »slot«, disregarding the possibility of permutations. Similar to `NodeBuilder`, a policy template is used to pass down the setup for an actual custom allocator.
