- * MOZ_PASTE_PREFIX_AND_ARG_COUNT(aPrefix, ...) counts the number of variadic
- * arguments and prefixes it with |aPrefix|. For example:
- *
- *   MOZ_PASTE_PREFIX_AND_ARG_COUNT(, foo, 42) expands to 2
- *   MOZ_PASTE_PREFIX_AND_ARG_COUNT(A, foo, 42, bar) expands to A3
- *
- * You must pass in between 1 and 50 (inclusive) variadic arguments, past
- * |aPrefix|. It is not legal to do
- *
- *   MOZ_PASTE_PREFIX_AND_ARG_COUNT(prefix)
- *
- * (that is, pass in 0 variadic arguments). To ensure that a compile-time
- * error occurs when these constraints are violated, use the
- * MOZ_STATIC_ASSERT_VALID_ARG_COUNT macro with the same variaidc arguments
- * wherever this macro is used.
- *
- * Passing (__VA_ARGS__, <rest of arguments>) rather than simply calling
- * MOZ_MACROARGS_ARG_COUNT_HELPER2(__VA_ARGS__, <rest of arguments>) very
- * carefully tiptoes around a MSVC bug where it improperly expands __VA_ARGS__
- * as a single token in argument lists. For details, see:

- * MOZ_STATIC_ASSERT_VALID_ARG_COUNT ensures that a compile-time error occurs
- * when the argument count constraints of MOZ_PASTE_PREFIX_AND_ARG_COUNT are
- * violated. Use this macro wherever MOZ_PASTE_PREFIX_AND_ARG_COUNT is used
- * and pass it the same variadic arguments.
- *
- * This macro employs a few dirty tricks to function. To detect the zero
- * argument case, |(__VA_ARGS__)| is stringified, sizeof-ed, and compared to
- * what it should be in the absence of arguments.
- *
- * Detecting too many arguments is a little trickier. With a valid argument
- * count and a prefix of 1, MOZ_PASTE_PREFIX_AND_ARG_COUNT expands to e.g. 14.
- * With a prefix of 0.0, it expands to e.g. 0.04. If there are too many
- * arguments, it expands to the first argument over the limit. If this
- * exceeding argument is a number, the assertion will fail as there is no
- * number than can simultaneously be both > 10 and == 0. If the exceeding
- * argument is not a number, a compile-time error should still occur due to
- * the operations performed on it.
