What does this do on integer overflow? Should you validate that the
result fits in [u]int64_t? Should you allow for a leading '-' sign for
a default of a negative number? You have forbidden '0' as a valid
number (although you correctly forbid '00' and any non-zero number with
a leading 0, which matches JSON restrictions).

Again, this forbids the use of '0' as a default.
