First off, private/protected probably does not mean what you think it
does (ie it's not the same as in C++ or java).
For example:
class A
private
def a_private_method
puts "hi"
end
protected
def a_protected_method
puts "ho"
end
end
class B< A
def foo
a_private_method
end
def bar
A.new.a_private_method
end
def baz
A.new.a_protected_method
end
end
B.new.foo #=> "hi"
B.new.bar #=> NoMethodError: private method `a_private_method' called
for #<A:0x6452c>
B.new.baz #=> "ho"
On top of that, filters eventually use the send method, which ignores
protected/privateness
