Sigh.  Nonsense.  I use octal notation *every day*, for two extremely
prevalent purposes: file creation umask, and Unix file permissions
(i.e. the chmod() function/command).  

I fail to see how 0O012, or even 0o012 is more intelligible than 012.
The latter reads like a typo, and the former is virtually
indistinguishable from 00012, O0012, or many other combinations that
someone might accidentally type (or intentionally type, having to do
this in dozens of other programming languages).  I can see how 012 can
be confusing to new programmers, but at least it's legible, and the
great thing about humans is that they can be taught (usually).  I for
one think this change is completely misguided.  More than flushing out
bugs, it will *cause* them in ubiquity, requiring likely terabytes of
code to be poured over and fixed.  Changing decades-old behaviors
common throughout a community for the sake of avoiding a minor
inconvenience of the n00b is DUMB.
