I second your example of:

  def foo
    ...
    yield stuff if block_given?
  end

versus:

  def foo(&blk)
    ...
    blk.call(stuff) unless blk.nil?
  end

I think I would have found iterators much easier to get my head round if I
had seen the second, rather than the first, initially.

And if you use the first syntax, there is the leap you have to make sooner
or later: "hang on - how do I pass this block to another method?"; or
conversely, "I have a proc object, but how do I pass it to a method which
expects a block?"

Brian.
