I have just started learning Ruby and I am going through as much documentation as I can find. The only question that I cannot seem to find an answer to concerns the use of the # symbol when referring to methods (I think I've seen it used to refer to both class and instance methods). Here is an example: http://www.rubycentral.com/book/ref_c_io.html#IO.select On the above page there is a link to "Kernel#select" which is a class method. and here: http://www.rubycentral.com/book/ref_c_object.html#Object.is_a_qm There is a link to "Object#kind_of?" which is an instance method. Clearly the purpose of the hash mark has another purpose. Anyone know what document explains this? Thanks! Justin -- Posted via http://www.ruby-forum.com/.
