title: ruby debugger step into a block directly?
body: <p>In the following Ruby code:</p>
  
  <pre><code>#! /usr/bin/env ruby
  
  require 'debugger'
  
  def hello
    puts "hello"
    if block_given?
      yield
    end 
  end 
  
  def main
    debugger
    puts "test begin..."
    hello do   # &lt;=  if you are here
      puts "here!" #&lt;= how to get here without setting bp here or step into hello?
    end 
  end 
  
  main
  </code></pre>
  
  <p>It's very common during debugging, I don't care about the implementation of the function that yields to the block, I just want to step into the block directly, without manually setting a break-point there.</p>
  
  <p>Does any support for this kind of "step into block" exist in ruby-debug19 or debugger?</p>
