Would it be fair to say (or completely out to lunch) that a local
variable is local to a method and an instance variable is local to an
object. Thus an instance variable is a sort of limited global
variable or super-powered local variable. Its scope is larger than a
local but smaller than a global. Or that it is a global within a
limited domain (the object).
or is it a whole lot deeper than that?
I am told that the Hindus believe that God is near us always but a
veil of delusion hides his glory from our eyes. I feel the same way
about rails except that it is a veil of CONfusion that hides its
glory from me. I believe its glory is there, waiting to be felt.
