Undocumented features of String#oct
String#oct will adjust the base of the stringy number being converted to 2 (if prefixed with 0B), 8 (also the default, if prefixed with 0O), 10 (if prefixed with 0D), or 16 (if prefixed with 0X). Much to my surprise this behavior is not documented at ruby-doc.org . Is this the intended behavior and if so should the documentation be updated? If it is not the intended behavior, perhaps String#oct should raise an exception if someone tries to use this undocumented feature?

It is surprising for me too. But this behavior was introduced in r373 by intention.
I hope Matz remembers the original intention.
I guess Ruby followed the behavior of Perl and it was useful to handle string representation of file permissions?
