Hows this for a less than sophisticated attempt

class Dog
def bark
puts "WOOF"
end
end

class Proxy
def initialize(clazz)
@clazz =3D clazz
end

def method_missing(meth, *parms)
@precall.call(meth, *parms)
@clazz.send(meth.to_s, *parms)
end

def precall(&block)
@precall =3D block
end

end

d =3D Dog.new
d.bark

pro=3DProxy.new(d)
pro.precall { |meth,parms|
puts "Precall method #{meth.to_s}"
}

pro.bark
