| * @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 |
