Subject: Why does this use a block

So I'm new to Ruby and I'm trying to use OptionParser to parse in some
command line arguments. I looked at some documentation on OptionParser and
there is something that's confusing me to no end. In all the examples a
block is being passed in to the constructor of the OptionParser object. The
constructor simply makes a yield call, passing self as an argument. 

What is the point of this? Can we not convert

opts = OptionParser.new() {|opts| body}

To

opts = OptionParser.new()
body

? This seems more natural to me. But the former seems like a common Ruby
idiom so I'm wondering what I am missing.

Thanks,
