::That said, note that this point of view is that you cannot pass an object to a method. --[[User:Rdm|Rdm]] 12:33, 11 August 2011 (UTC)
:::Right; not only can you not pass an object, the point of view is that no expression in the language has the value of an object, only the value of a reference. This is the same point of view as in Java, Python, etc. Whatever we decide has to be consistent across all these languages. --[[User:Spoon!|Spoon!]] 19:44, 11 August 2011 (UTC)
== Phantom categories and Ruby's standard library ==
A few parts of Ruby's standard library have their own categories.
# <code>require 'curses'</code> => [[:Category:Curses]]
# <code>require 'rexml/document'</code> => [[:Category:REXML]]
# <code>require 'tk'</code> => [[:Category:Ruby/Tk]]
I am not wanting categories for most other parts of the standard library. I destroyed 11 ''phantom categories'' by removing all their members.
# Category:bigdecimal (2 members)
# Category:complex.rb (1 member)
# Category:dRuby (1 member)
# Category:fileutils.rb (1 member)
# Category:mathn (1 member)
# Category:matrix (2 members)
# Category:matrix.rb (3 members)
# Category:minitest (1 member)
# Category:optparse (1 member)
# Category:prime (1 members)
# Category:test/unit (2 members)
A ''phantom category'' is a category with some members, but no category page. Templates like <nowiki>{{libheader|prime}}</nowiki> did put pages in these categories. I started to destroy these categories after someone confused Category:prime with [[:Category:Prime Numbers]] ([[Rosetta Code:Village Pump/Grouping tasks#Library/Libheader appears to be being used incorrectly|ref 1]] and [[Talk:Count in factors#phantom categories - incorrect use of Library templates|ref 2]]). I think that many contributors will use the standard library without adding categories. I see code that calls <code>require 'find'</code> or <code>require 'securerandom'</code> without a category. --[[User:Kernigh|Kernigh]] 03:49, 27 August 2011 (UTC)
