Other Forms of Assignment

In common with many other languages, Ruby has a syntactic shortcut: a=a+2 may be written as a+=2.

The second form is converted internally to the first. This means that operators that you have defined as methods in your own classes work as you'd expect.

class Bowdlerize
  def initialize(aString)
    @value = aString.gsub(/[aeiou]/, '*')
  def +(other) + other.to_s)
  def to_s
a ="damn ") d*mn
a += "shame" d*mn sh*m*
