Is there any English written that describes the finer details of Ruby.  =
I find myself running into questions that happen due to missing some =
fundamental holes in my understandings.

Things like a Meta Classes methods are the methods it inherited from the =
Class class and it's parent class, it's instance methods are are the =
methods added in it's declaration.

$_ is not a global variable

Adding a method to Kernel sees different global variables than =
Kernel.instance_eval

All unscopped code runs in the scope of a global instance of Object.

class << self can be used to create instance methods for a meta class.

I know that some of this is incorrect, or misguided, or untrue so any =
pointers greatly appriciated.

I will compile a list of anything I find and put it on a web page =
somewhere.

Ralph
