-- Per-param modifiers, which can be specified either as separate parameters (e.g. t2=, pos3=) or as inline modifiers
-- <t:...>, <pos:...>, etc. The key is the name fo the parameter (e.g. "t", "pos") and the value is a table with
-- elements as follows:
-- * `extra_specs`: An optional table of extra key-value pairs to add to the spec used for parsing the parameter
-- when specified as a separate parameter (e.g. {type = "boolean"} for a Boolean parameter, or
-- {alias_of = "t"} for the "gloss" parameter, which is aliased to "t"), on top of the default, which
-- is {list = true, allow_holes = true, require_index = true}.
-- * `convert`: An optional function to convert the raw argument into the form passed to [[Module:affix]].
-- This function takes four parameters: (1) `arg` (the raw argument); (2) `inline` (true if we're
-- processing an inline modifier, false otherwise); (3) `term_index` (the actual index of the first term);
-- (4) `i` (the logical index of the term being processed, starting from 1).
-- * `item_dest`: The name of the key used when storing the parameter's value into the processed `parts` list.
-- Normally the same as the parameter's name. Different in the case of "t", where we store the gloss in
-- "gloss", and "g", where we store the genders in "genders".
-- * `param_key`: The name of the key used in the `params` spec passed to [[Module:parameters]]. Normally the same as
-- the parameter's name. Different in the case of "lit", "sc", etc. where e.g. we distinguish per-term
-- parameters "lit1", "lit2", etc. from the overall parameter "lit".

-- Parse raw arguments in `args`. If `extra_params` is specified, it should be a one-argument function that is called
-- on the `params` structure before parsing; its purpose is to specify additional allowed parameters or possibly disable
-- parameters. If `has_source` is given, there is a source-language parameter following 1= (which becomes the
-- "destination" language parameter) and preceding the terms. This is currently used for {{pseudo-loan}}. All language
-- parameters are allowed to be etymology-only language. Returns five values ARGS, TERM_INDEX, LANG_OBJ, SCRIPT_OBJ,
-- SOURCE_LANG_OBJ where ARGS is a table of the parsed arguments; TERM_INDEX is the argument containing all the terms;
-- LANG_OBJ is the language object corresponding to the language code specified in 1=; SCRIPT_OBJ is the script object
-- corresponding to sc= (if given, otherwise nil); and SOURCE_LANG_OBJ is the language object corresponding to the
-- source-language code specified in 2= if `has_source` is specified (otherwise nil).
