Hi,

We can dynamically include a module in a class as…

class A

module B  
def method\_of\_b  
end  
end

end

a = A.new  
a.class.send :include, B

Is there any way to remove the dynamically included module from a class.

In short, no. The language does not allow removing mixins any more than  
it  
allows removing a class’s superclass. Individual methods can be removed,  
however, using undef or remove\_method.
