A way to express rules for how to translate names from the Inter namespace into the target language's namespace.

§1. This section of code is pleasingly simple: it has no functionality, and exists as a stand-alone section just to give these functions legible names. 

    typedef struct name_translation {
        struct text_stream *translate_to;
        int then_make_unique;
        struct inter_name_generator *name_generator;
        int derive;
        int by_imposition;
    } name_translation;

    name_translation Translation::same(void) {
        name_translation nt;
        nt.translate_to = NULL;
        nt.then_make_unique = FALSE;
        nt.name_generator = NULL;
        nt.derive = FALSE;
        nt.by_imposition = FALSE;
        return nt;
    }

    name_translation Translation::uniqued(void) {
        name_translation nt = Translation::same();
        nt.then_make_unique = TRUE;
        return nt;
    }

    name_translation Translation::imposed(void) {
        name_translation nt = Translation::same();
        nt.by_imposition = TRUE;
        return nt;
    }

    name_translation Translation::to(text_stream *S) {
        name_translation nt = Translation::same();
        nt.translate_to = S;
        return nt;
    }

    name_translation Translation::to_uniqued(text_stream *S) {
        name_translation nt = Translation::same();
        nt.translate_to = S;
        nt.then_make_unique = TRUE;
        return nt;
    }

    name_translation Translation::prefix(text_stream *S) {
        name_translation nt = Translation::same();
        nt.name_generator = InterNames::multiple_use_generator(S, NULL, NULL);
        nt.derive = TRUE;
        return nt;
    }

    name_translation Translation::suffix(text_stream *S) {
        name_translation nt = Translation::same();
        nt.name_generator = InterNames::multiple_use_generator(NULL, NULL, S);
        nt.derive = TRUE;
        return nt;
    }

    name_translation Translation::generate(text_stream *S) {
        name_translation nt = Translation::same();
        nt.name_generator = InterNames::multiple_use_generator(NULL, S, NULL);
        return nt;
    }

The function Translation::same is used in 1/hl (§3), 3/pi (§3).

The function Translation::uniqued appears nowhere else.

The function Translation::imposed appears nowhere else.

The function Translation::to appears nowhere else.

The function Translation::to_uniqued appears nowhere else.

The function Translation::prefix appears nowhere else.

The function Translation::suffix appears nowhere else.

The function Translation::generate appears nowhere else.

The structure name_translation is accessed in 1/hl and here.
