dependencies:

iterateTermOther is called using makeDepend and addOther
subtermUnify is called using unifiesWithKeys
term_iterate_open_leaves is called using addsubterms
unify is called using unify_combine_enc and unify_combined_tup, and a callback using the keys list? (which propagates back to subtermunify data)
