I think I start getting how it works. However, the dependency between statement and expression is not circular in calc7: expression seems to have no knowledge about statement.
So if my dependency is circular (like e.g. expression and factor in calc2_ast), is it possible to separate them, as you suggest?
Also, is there any documentation for calc7 or about TUs (what does TU mean?)?
Again, many thanks for your kind answers.
