Very nice.

Yes, I know some compiler hackers have found it useful. And I was a
little sad nobody had time to keep dwarflint up to date. It is really
great to hear you have.

Yes please do share. I cannot promise to have a lot of time reviewing
the code. But I am certainly interested. Creating a public "dwarflint"
branch sounds like a good idea.

Could you take a look at the CONTRIBUTING file? We don't have to be
very formal for code not directly going onto master. But having at
least a Signed-off-by line on the patches makes sure we can eventually
integrate them officially.

Thanks,

Mark
