Hey Zhenning Guan,

Hope the following sample will help you,

def in(options)
  p options.class
end
in(:say => 'some_value')

the type of argument passed to any method resembles inside the method, 
if you send hash it shows the class as 'Hash'. No need to initialize 
hash or anything in ruby script. It will assign automatically according 
to the values.

thanks,
vaddi
