the above is essentially "class metadata".

but it gives me the basic idea:

class Object
   def meta() @meta ||= {} end
end

talker.sayYourName.meta[:author] = "it's just me"
puts talker.sayYourName.meta[:author]
=> it's just me

[i like this language *very* much]

-

But to understand this fully, can someone please decrypt this:

   def meta()
     @meta ||= {}
   end

..
