Re: Compiler plugin for warning suppression

Awesome -- I'm really glad you picked this up!

We're actually in favor of making reporting configurable (that "won't fix"
ticket is a bit overloaded). I actually refactored quite a bit of code
<http://11bfa25e37> to enable this a while ago, but didn't get around to
implementing the user-facing part.

If you're willing to do the work, I'd be happy to merge this plugin into
the standard 2.11.x compiler (albeit under a -Xreporter switch). Ideally,
we should SIP a reporting configuration mechanism for 2.12.

thank you!
