class A
...
end

t = A.new
class << t
	def hack
	end
end

This is a singleton hack. But

class A
	class << self
		def someclassmethod
		end	
	end
end

is none. It's just another way of saying def A.someclassmethod. I kind
of like the class << self idiom because it should be natural to people
at ease with the language. And it makes think the rest about it,
especially because it is well documented (see link posted earlier).

I don't get the point of this being *code smell*.

About the properties:
Yes, they are a third leg, and they must go away. But we will need a
kind of runtime configuration that is common to all applications that
can be changed indepently of code, this is needed for deployment (stage,
test, live, ...). I would appreciate work being done on a configuration
system that we call could reuse in our own apps, and one that includes
Borges config. There certainly is a common need for this.

The fact that they are hot-changeable is nice too, but the admin/seaside
has to go.

I am meaning no insult by my remarks about the class << self; however I
find that to be valid Ruby code. Excuse me if it comes across as one.

best regards,
