O_O They've intentionally coded it that way? This is atrocious. And this hand-rolled mess that doesn't even parse numbers correctly! It would parse "099" as 81

O_O They've intentionally coded it that way? This is atrocious. And this hand-rolled mess that doesn't even parse numbers correctly! It would parse "099" as 81 and "99999999999999999" as whatever it is modulo (MAX_ULONG+1), without any overflow detection. Well, at least they don't accept negative numbers, that's something. Anf mind you, beauty of C pointers has nothing to do with neither of these two bugs not the original decision to support octals and hexadecimals.
