Re: Compiler plugin for warning suppression

I'm really happy to see that Scala is open for that feature. From various 
discussions I kind of deduced that warning suppression is considered bad 
and that's why it isn't there.
I will try to dig a bit into the compiler and see what I can do, but it 
seems to me that native implementation would have to be done differently 
than what's currently in the plugin.
