Hi,

how do I remove all my class methods like in the following example? –

class Parent  
class \<\< self  
def class\_stuff  
puts “Stuff from my class”  
end  
end  
end

class Child \< Parent

# remove all the class methods;

# should be done automatically with "…methods.each { |m|

remove\_method(m) }"-like construct  
end

Many thanks in advance.

dodeantn,  
This will do it but I would prefer a better way…

class Parent  
(class \<\< self; self; end).send(:remove\_method, :class\_stuff)  
end

Please remember that with great power comes great responsibility… 🙂  
messing with class methods is a real pain in 1.8 but maybe I am missing  
the boat…
