you assume that it's a hierarchy, but it's not.
irb(main):009:0> Person.new.man
=> nil
irb(main):010:0> Person.new.man.author
NoMethodError: undefined method `author' for nil:NilClass
from (irb):10
from :0
irb(main):011:0> Person.new.author
"I am author"
=> nil
the chain seems to work on plain defs since by default if you do not
specify a class, ruby creates it in Object class. Thus the methods
defined are Object methods, ergo they become "public" so to speak.
Thus even nil class acquired the reader/author method; thus exhibiting
the seemingly hierachical behaviour (see my prev post). There is no
function as function per se in ruby. There are only methods wc of
course belong to a class.
