Subject: Keywords, &blocks and instance_eval

Hi

I am fine tuning a DSL and came across the situation
where I needed a method with the name of 'module'.

In my previous revision of the DSL, I did the following:

------------
  class C
    def initialize
      yield self
    end
    def module
      puts "in C#module"
    end
  end
-------------

The user code would then look like:

  C.new do |c|
    c.module
  end

But, I didn't really like requiring (or explaining)
why the 'c.' was required. So I rewrote the class to be:

------------
  class C
    def initialize(&block)
      instance_eval &block
    end
    def module
      puts "in C#module"
    end
  end
-------------

But, when a method name is called that is dear to Ruby heart,
like 'module', an error is generated:

  C.new do
    module
  end       #=> syntax error

Is there any way to have get the effect of the above

 c.module

with the instance_eval?

Thanks
