-- For a given gender/number combination, parse and return the full set

-- "mod" key for the first modifier (see below), a "mod2" key for the
-- second modifier, etc. listing all stems for both the base and modifier(s).
-- The value of each key is a "stem-type list", i.e. an array of stem-type
-- pairs, where each element is a size-two array of {COMBINED_STEM, STEM_TYPE}.
-- COMBINED_STEM is a stem with attached transliteration in the form
-- STEM/TRANSLIT (where the transliteration is either manually specified in
-- the stem argument, e.g. 'pl=لُورْدَات/lordāt', or auto-transliterated from
-- the Arabic, with BOGUS_CHAR substituting for the transliteration if
-- auto-translit fails). STEM_TYPE is the declension of the stem, either
-- manually specified, e.g. 'بَبَّغَاء:di' for manually-specified diptote, or
-- auto-detected (see stem_and_type() and detect_type()).
--
-- DATA and ARGS are as in init(). ARGPREFS is an array of the prefixes for
-- the argument(s) specifying the stem (and optional translit and declension
-- type). For a given ARGPREF, we check ARGPREF, ARGPREF2, ARGPREF3, ... in
-- turn for the base, and modARGPREF, modARGPREF2, modARGPREF3, ... in turn
-- for the first modifier, and mod2ARGPREF, mod2ARGPREF2, mod2ARGPREF3, ...
-- for the second modifier, etc. SGS is a stem specification (see above),
-- giving the stems that are used to base derived forms off of (e.g. if a stem
-- type "smp" appears in place of a stem, the sound masculine plural of the
-- stems in SGS will be derived). DEFAULT is a single stem (i.e. a string) that
-- is used when no stems were explicitly given by the user (typically either
-- "f", "m", "d" or "p"), or nil for no default. ISFEM is true if we're
-- accumulating stems for a feminine number/gender category, and NUM is the
-- number (expected to be "sg", "du" or "pl") of the number/gender category
-- we're accumulating stems for.
--
-- About bases and modifiers: Note that e.g. in the noun phrase يَوْم الاِثْنَيْن
-- the head noun يَوْم is the base and the noun الاِثْنَيْن is the modifier.
-- In a noun phrase like البَحْر الأَبْيَض المُتَوَسِّط, there are two modifiers.
-- Note that modifiers come in two varieties, adjectival modifiers and
-- construct (ʾidāfa) modifiers. The first above noun phrase is an example
-- of a noun phrase with a construct modifier, where the base is fixed in
-- the construct state and the modifier is fixed in number and case
-- (which is always genitive) and possibly in state. The second above noun
-- phrase is an example of a noun phrase with two adjectival modifiers.
-- A construct modifier is generally a noun, whereas an adjectival modifier
-- is an adjective that usually agrees in state, number and case with the
-- base noun. (Note that in the case of multiple modifiers, it is possible
-- for e.g. the second modifier to be an adjectival modifier that agrees
-- with the first, construct, modifier, in which case its case will be fixed
-- to genitive, its number will be fixed to the same number as the first
-- modifier and its state will vary or not depending on whether the first
-- modifier's state varies. It is not possible in general to distinguish
-- adjectival and construct modifiers by looking at the values of
-- modN_state, modN_case or modN_number, since e.g. a third modifier could
-- have all of them specified and be either kind. Thus we have modN_idafa,
-- which is true for a construct modifier, false otherwise.)

-- this is a plural argument. WORD may be of the form ARABIC, ARABIC/TR,
-- ARABIC:TYPE, ARABIC/TR:TYPE, or TYPE, for Arabic stem ARABIC with
-- transliteration TR and of type (i.e. declension) TYPE. If the type
-- is omitted, it is auto-detected using detect_type(). If the transliteration
-- is omitted, it is auto-transliterated from the Arabic. If only the type
-- is present, it is a sound plural type ("sf", "sm" or "awn"),
-- in which case the stem and translit are generated from the singular by
-- regular rules. SG may be of the form ARABIC/TR or ARABIC. ISFEM is true
-- if WORD is a feminine stem. NUM is either "sg", "du" or "pl" according to
-- the number of the stem. The return value will be in the ARABIC/TR format.

-- POS is the part of speech, generally "noun" or "adjective". Used to
-- distinguish nouns and adjectives of the فَعْلَان type. There are nouns of
-- this type and they generally are triptotes, e.g. قَطْرَان "tar"
-- and شَيْطَان "devil". An additional complication is that the user can set
-- the POS to something else, like "numeral". We don't use this POS for
-- modifiers, where we determine whether they are noun-like or adjective-like
-- according to whether mod_idafa= is true.
