cyclic dependencies should work agreed, but I couldn't easily follow the
dependencies you created in your program.

even more, all your import are plain imports :-)
you'd better use "private import ..."
that prevents symbols imported in a module for it's internal
implementation to leak through to other modules.

an example:
module A import module B
module B import module C
=> all public definitions in module C are now available in module A
=> the definitions in C are available in B and in A

or:
module A private import module B
module B private import module C
=> only symbols defined in B are available in A
=> C symbols are not available in A
=> you wish C in A, do a new private import I'd say
