The most stylish, Ruby way to do what you are trying to do is as follows:

class MyClass

  def initialize
    @myVar1 = 0 # direct value manipulation
    self.myVar1 = 1 # sent through your wrapper
    puts @myVar1
  end

  def myVar1=(value)
    @myVar1 = value
    # process extra steps here
  end

end

(Ehm, I should admit, there may be a better way to actually get the
accessor method to fire inside of initialize than self.myVar1, but
that's what I found to work.)
