/**
 * DOC: C preprocessor metaprogramming framework
 *
 * This section implements a portable ``FY_CPP_*`` macro toolkit that enables
 * applying an operation to every argument in a ``__VA_ARGS__`` list — the
 * equivalent of a compile-time ``map()`` function.
 *
 * **Implementation**: arity dispatch.  The number of arguments is counted
 * positionally (``_FVN``) and pasted onto a per-arity worker macro
 * (``_FM_1`` .. ``_FM_64``), each of which handles one element and chains to
 * the next-lower arity.  No token stream is ever re-scanned, so the expansion
 * cost is linear in the output size.  (The previous implementation forced up
 * to 64 re-expansion passes via an ``FY_CPP_EVALn`` ladder, which exhausted
 * Clang's source-location address space on large translation units:
 * "fatal error: translation unit is too large for Clang to process".)
 *
 * The maximum list length is **64 arguments** on all compilers.  Exceeding it
 * (up to 96) produces a compile error mentioning
 * ``FY_CPP_MAP_too_many_arguments``.  The tables are mechanical and can be
 * extended if ever needed.
 *
 * **Argument accessors** — extract positional arguments from ``__VA_ARGS__``:
 *
 * - ``FY_CPP_FIRST(...)``  — first argument (0 if list is empty)
 * - ``FY_CPP_SECOND(...)`` — second argument
 * - ``FY_CPP_THIRD(...)``  — third argument
 * - ``FY_CPP_FOURTH(...)`` — fourth argument
 * - ``FY_CPP_FIFTH(...)``  — fifth argument
 * - ``FY_CPP_SIXTH(...)``  — sixth argument
 * - ``FY_CPP_REST(...)``   — all arguments after the first (empty if < 2)
 *
 * **Map operations**:
 *
 * - ``FY_CPP_MAP(macro, ...)`` — expand ``macro(x)`` for each argument @x.
 * - ``FY_CPP_MAP2(a, macro, ...)`` — expand ``macro(a, x)`` for each @x,
 *   threading a fixed first argument @a through every call.
 *
 * **Utility**:
 *
 * - ``FY_CPP_VA_COUNT(...)``         — number of arguments (integer expression).
 * - ``FY_CPP_VA_ITEMS(_type, ...)``  — compound-literal array of @_type from varargs.
 *
 * **Legacy helpers** kept for source compatibility (no longer used by the
 * map machinery itself): ``FY_CPP_EVALn``/``FY_CPP_EVAL`` (forced
 * re-expansion passes), ``FY_CPP_EMPTY()``, ``FY_CPP_POSTPONE1/2()``.
 *
 * **Example**::
 *
 *   // Count and collect variadic integer arguments into a C array:
 *   int do_sum(int count, int *items) { ... }
 *
 *   #define do_sum_macro(...) \
 *       do_sum(FY_CPP_VA_COUNT(__VA_ARGS__), \
 *              FY_CPP_VA_ITEMS(int, __VA_ARGS__))
 *
 *   // do_sum_macro(1, 2, 5, 100) expands to:
 *   // do_sum(4, ((int [4]){ 1, 2, 5, 100 }))
 */

// C preprocessor magic follows (pilfered and adapted from h4x0r.org)

/* applies an expansion over a varargs list */

/*
 * FY_CPP_SHORT_NAMES is kept defined for compatibility: libfyaml-generic.h
 * selects its short-name item-builder branch based on it.  The short internal
 * names (_FM, _FM2, _FVC, ...) are the only implementation now.
