Yes, I guessed as much. Which brings up a question of what
exactly octal deprecation will entail.
The goal here is to make sure things either do what they
look like, or don't compile.
010 doesn't do what it looks like to a person used to
decimal; it is a C octal literal for decimal 8.
So it is deprecated.
But, making it mean decimal 10 is also a no go, because
if you're used to C syntax, it won't do what you expect.
That's why it is an error. It is sure to confuse *somebody*.
01, 02, 03, ... 07 though work in both cases, so they
might still be allowed. (I'm not sure if they are or not).
But since there's no confusion for decimal people or for
C people, there's no problem with those small numbers.
Also, string escape sequences appear to allow backslash octal
as well;
are these being deprecated or are they here to stay?
I'm not sure.
