A modern programming language that makes developers happier.

yesterday I made some progress. it looks like we need a tree with weighted edges, at least this was the most plausable structure I found. the new implementation traverses the tree in correct order. it pays attention to `setup()`s of parent `Node`s and places them before `setup()`s of the current `Node`. it is also possible to propagate and transform the tree `Node` after `Node`. this is required because propagating a subtree means we also execute some parts of the specification itself.
