Does int128() and uint128() croak for "0400000000000000000000000000000000000000"?
Does $x + undef and the like warn? (Note that «undef + $x» cannot warn without making «my $x; $x += int128(...)» warn.)
Does signed to unsigned promotion occur when required? (e.g. when adding two a large number overflows.)
Does unsigned to signed promotion occur when required? (e.g. when subtraction overflows to something negative.)
Are the string buffers always suitably aligned for a int128_t? (You use memcpy in some spots, but casts in others.)
