Kavorka traits are not supported

Something like the following will cause tidying to error

method foo () but begin { 'bar' }

I'm not that familiar with Kavorka traits. I've just committed changes that add basic support for is/does/but. I'd appreciate any feedback.

Me either, just started using them the otherday. Thanks for taking a look at this

The changes and the test look like they capture my usage 👍
