True. My goal is to get the simplest possible thing working now, and then before beta 2 fix it so that backslashes again work in the text portions of an f-string. After that, I'll fix this particular piece of code (and the others, plus the tests that can be made to work).

Here's an updated patch. I'm planning on committing it today.
