"If no Base is given, the parseInt function decides what base the number
is in by looking at the number. It assumes that any number beginning
with 0x is Hexadecimal, and may assume that any number beginning with 0
is Octal. To remove this ambiguity, always use the Radix parameter with
parseInt".

Naive. There are circumstances in which it is right for the user to
choose the base from 8, 10, 16. Don't be a Stalinist.
