--- Comment #10 from Kan Liu <kan.liu.229 at gmail dot com> --- (In reply to Jonathan Wakely from comment #9) > I can see one good reason to implement those operators as templates: it > allows us to check if the literal value overflows the duration::rep type, > which is required by the standard but impossible to implement without using > templates. _Select_type already does the overflow check, so *template implemented operators* is still redundant I think. Since the standard units (std::hours, milliseconds ...) requires the duration::rep to be *int64_t*, there's no need to do too much check.
