Ruby fs watcher?

newbie q on class Foo::Bar
222106 [matt@ti bi s] What's the point of a class-within-a-class? For example, I take it that
222111 [nospam@no it] One reason is to create a class that is private. You may be aware that one
222113 [dblack@wo bl] The nesting won't give you privacy, though; the class can still be

why is my singleton method called before the class is initialize?
222186 [bachase@gm i] class BigGuy
222187 [matt@ti bi s] "Initialize" is called when the class is instantiated (i.e. with new).
222188 [rick.denatal] True, but kind of beside the point.  The initialize method if and when
222200 [matt@ti bi s] Perhaps it's a matter of pedagogy. What *is* "the point"? That depends
222203 [bachase@gm i] I'll say thanks to both of you.  I think I was confused on all

  | + 222511 [logancapaldo] problem = ''
  |   222555 [gregory.t.br] Besides, we already have syntax that prevents this from being terribly
  + 222525 [vidar@ed ei ] It is consistent. "to_s" returns a string representation of the

Singleton Methods
222217 [bparanj@gm i] What is the purpose of singleton method? Why is singleton method
