Feature request: add mixin hook similar to method_added and included

[kristianmandrup]

module Mixology
def mixin(mod)
unmix mod
reset_method_cache
IncludedModule.new(mod).attach_to metaclass
reset_method_cache
mixed_in(self)
self
end

def unmix(mod_to_unmix)
last_super = metaclass
this_super = metaclass.direct_superclass
while this_super
break if this_super == self.class
if (this_super == mod_to_unmix ||
this_super.respond_to?(:module) && this_super.module == mod_to_unmix)
reset_method_cache
last_super.superclass = this_super.direct_superclass
reset_method_cache
mixed_out(self)
return self
else
last_super = this_super
this_super = this_super.direct_superclass
end
end
mixed_out(self)
self
end

def mixed_out(obj)
end

def mixed_in(obj)
end
...

But trying to get it to work on my local machine doesn't seem to work!?
I really need such hooks... could I somehow use the included hook instead?

This will do what you want: http://gist.github.com/240872 I'll try to get something in mixology officially later.
