Subject: [ruby-core:55601] [ruby-trunk - Feature #8563] Instance variable arguments


Issue #8563 has been updated by matz (Yukihiro Matsumoto).


From my POV:

  def initialize(@foo, @bar)
  end

does not express intention of instance variable initialization.  I'd rather add a method like

  define_attr_initialize(:foo, :bar)

to define a method of

  def initialize(foo, bar)
    @foo = foo
    @bar = bar
  end

Matz.

=begin
Often times, people want to assign given arguments to instance variables, especially inside the method `initialize`:

    def initialize foo, bar, buz
      @foo, @bar, @buz = foo, bar, buz
      ...
    end

I propose to let method definition take instance variables as arguments so that:

    def initialize @foo, @bar, @buz
      ...
    end

would be equivalent as above.
