Comment #4 on issue 291 by [email protected]: array indexes are always
of type string
http://code.google.com/p/v8/issues/detail?id=291
Note that multiplying the key by one isn't necessarily the cleanest way of
converting
a string to a number. I'd go for using the unary + operator like:
print(+k + 2);
or maybe even use Number(k) to make it less magical:
print(Number(k) + 2)
See ECMA-262, 3rd edition, section 11.4.6 ("Unary + Operator") on page 47
and section
15.7.1.1 ("Number([value])") on page 107.
