i always define this in lib/rubyext.rb
def singleton_class &b
sc =
class << self
self
end
b ? module_eval(&b) : sc
end
then
singleton_class.attr_accessor 'foo'
or, better
singleton_class do
attr 'a'
attr 'b'
end
it's a sin to define a method that has a compelling use for a block
to silently ignore said block.
another thing i use often is attributes, this lets you do this
singleton_class do
attribute 'foo'
end
which gives
self.foo = 42 #=> @foo = 42
foo 42 #=> @foo = 42
foo #=> 42
foo? #=> true
it's attr_accessor in steriods and a very very short lib. (gem
install attributes)

we can deny everything, except that we have the possibility of being
better. simply reflect on that.
