+  // type 'T' might be to check into which of these subranges 's' falls
+  //    ... < T's lower bound <= ... <= T's upper bound < ...
+  // However, this approach is _incorrect_ when applied to generic code
+  //    if (s < T::lowest()) ... else if (s > T::highest()) ... else ...
+  // since 'S' and 'T' may be types of different signedness.
+  //
+  // Under ansi (and even more K&R) C promotion rules, if 'T' is unsigned
+  // and if there's no larger signed type available, the value 's' gets
+  // promoted to unsigned; then, a negative value of 's' becomes (large)
+  // positive -- with a wrong comparison outcome.
+  //
+  // Furthermore, the code should not trigger compiler warnings for any
+  // selection of integral types 'S', 'T' ("mixed signedness comparison",
+  // "comparison of unsigned expression <0 / >=0 is always false/true").
+  //
+  // The correct approach: do lower bound comparisons on signed types and
+  // upper bound comparisons on unsigned types only; this requires casts.
+  // For the casts to be safe, compare the value against the zero literal
+  //    if (s <= 0) { check as signed } else { check as unsigned }
+  // which is a valid + nontrivial test for signed and unsigned types.
+  //
+  // This implies that correct, generic conversion code must test into

+  //    ... < T's lower bound <= ... <= 0 < ... <= T's upper bound < ...
+  // while handling 's' as signed/unsigned where less-equal/greater zero.
