/** Boost.Parser uses assertions (`BOOST_ASSERT()`) in several places to
    indicate that your use of the library has an error in it.  All of those
    places could have instead been ill-formed code, caught at compile time.
    It is far quicker and easier to determine exactly where in your code such
    an error is located if this is a runtime failure; you can just look at the
    stack in your favorite debugger.  However, if you want to make these kinds
    of errors always ill-formed code, define this macro. */

/** Asserts that the given condition is true.  If
    `BOOST_PARSER_NO_RUNTIME_ASSERTIONS` macro is defined by the user,
    `BOOST_PARSER_ASSERT` expands to a compile-time `static_assert()`.
    Otherwise, it expands to a run-time `BOOST_ASSERT()`.  Note that defining
    `BOOST_DISABLE_ASSERTS` disables the use of C `assert`, even when
    `BOOST_ASSERT` is unavailable. */

    building in C++20 mode, if the compiler defines `__cpp_lib_concepts`.  To

    tuples.  It uses some metaprogramming to do this.  The technique used has
    a hard limit on the number of data members a struct can have.  Re-define
    this macro to change the hard limit.  Note that large values may increase
    compile times. */
