/// @assertion int parse(String source, {int radix, int onError(String source)})
/// Parse source as a, possibly signed, integer literal and return its value.
/// ...
/// If no radix is given then it defaults to 10. In this case, the source digits
/// may also start with 0x, in which case the number is interpreted as
/// a hexadecimal literal, which effectively means that the 0x is ignored and the
/// radix is instead set to 16.
/// ...
/// @description Checks that if no radix is given but there is 0x prefix that
/// mean that radix is 16
