Using 'Aroung Alias'

You can write an Around Alias in three simple steps:

1. You alias a method.
2. You redefine it.
3. You call the old method from the new method.

Example:

class String
alias :orig_length :length

def length
"Length of string '#{self}' is: #{orig_length}"
end
end

"abc".length => "Length of string 'abc' is: 3"
