Dear Dmitri, If it's only a small number of functions then move them the relevant functions for A to B so that B works without A. Then Import these functions from B in A. Hence A depends on B but B is independent of A.
It is requires to move a lot of functions than you better create a package C with all the common functions. Then A and B import those functions from C. Best regards, ir.
