Do you mean it changed the hask key to octal?
No. Hash keys and filenames are strings, not numbers, so the leading zero
does nothing in those cases and has no impact on your program. (Quite aside
from that, you also have only one digit after the zero, so these
numbers would be the same in octal as in decimal, except for 08 and 09,
which aren't even valid in octal and would therefore still be interpreted
as decimal, so there's another reason it has no impact.) He was just
making you aware for future reference that if you have something like '024'
and then treat it like a number (e.g., by adding another number to it),
the results may not be quite what you might expect. That's probably why
he called it a "small thing", because it doesn't have any impact on the
operation of your current program.
Sanity? Oh, yeah, I've got all kinds of sanity. In fact, I've developed whole new kinds of sanity. You can just call me "Mister Sanity". Why, I've got so much sanity it's driving me crazy.
