This would be great. I've done something similar to hack in JSX/Harmony support w/ blanket [here](https://github.com/danvk/mocha-react/blob/blanket/tests/blanket-stub-jsx.js).

@bsodzik can you say more about why clearing `require.cache` was insufficient to solve your problems? [Clearing it](https://github.com/danvk/mocha-react/commit/0ea74f2096b86294865bc1e39d49420c0fe03aee) in my `require.extensions` handler fixed a similar problem that I was having.

Gerrit doesn't seem to do this. Neither does Reviewable. I don't believe Critique did, either.

(an alternative way to implement this would be to make an effort to expand the diff hunk to include the function declaration)

Here's a [small demo](http://jsbin.com/xamidirifo/2/edit?html,css,js,output) based on how ReviewBoard handles this. The gist is that you style the left column cells to be un-selectable when the user clicks on the right...
