Subject: Re: yield self if block_given?

I tried below, it can work,


irb(main):001:0> class Myclass
irb(main):002:1>   def mya
irb(main):003:2>    yield self if block_given?
irb(main):004:2>   end
irb(main):005:1>   def myb
irb(main):006:2>    puts "it's myb"
irb(main):007:2>   end
irb(main):008:1> end
=> nil
irb(main):009:0>
irb(main):010:0* x=Myclass.new
=> #<Myclass:0x83f81b0>
irb(main):012:0> x.mya { puts "a"}
a
=> nil
irb(main):013:0> x.mya { |c| c.myb }
it's myb
=> nil

------
in the code above, what's "c" there?
does it mean the instance of x itself?

Thanks again.
