Backport #7843: A weird exception is raised when attempting to remove a "prepend"ed method

• Status: Closed
• Assignee: nagachika (Tomoyuki Chikanaga)

Hello,

module P
def m; puts "P"; super; end
end
class A
def m; puts "A"; end
prepend P
remove_method :m
#=> undefined method `method_removed' for #<A:0x007f9e1e825618>
end

Is this intentional?
