As to the lack of documentation. It's true that there's not a lot, but what's out there is good stuff. And the Pragmatic Programmer's guide may be a year old, but it most certainly is not a year out of date. After all, languages don't change that much.
It is possible to receive a block and then pass it on, it's just not introductory guide material. :-) Here's an example
When you talk about adding a local variable that masks calls to an earlier added function of the same name, you forget something: Ruby is an object-oriented langauge. You're supposed to call functions on objects, which can't be confused with a variable. In a class definition, you call one of that class's methods like self.method or like method, which is merely a shortcut for the former. It calls that method with that instance from the class.class Foo def initialize #no initialization needed for this class end def bar(&block) self.baz(&block) end def baz yield(3) end end foo = Foo.new foo.bar { |n| puts n } # prints "3\n"
This was also discussed at Ruby: An Abbot breaks silencewind. If you haven't checked it out, check it out. It's not better or worse than Perl -- it's different, and I love them both.
