Hi,

I’ve created this module to implement INotifyPropertyChanged in classes  
for  
databinding with WPF, but the way I’m handling the event seems a bit  
awkward. So I’m just checking if I’m doing it right. The lines of  
interest  
would be around line 76 of the link below

It looks good, but I think it’s somethign that should be implemented on  
a  
rubyism (irubysm?) like attr\_\*, so we can call a method “event x” to add  
the  
add\_x, remove\_x and raise\_x methods to that class.

Look out! Someone snuck in and put **python** in your nice ruby code!

Unless Ivan objects, I’m going to add this to a sample library I’m  
including in rc3. We can discuss moving it to core after post 1.0 plans  
are final.
