Conditional Tangling based on Tags

I recently came across a little-known (to me, anyway) feature of org mode, thanks to this mailing list reply: conditional tangling. In the :tangle argument, as well as the standard values (yes, no or a filename string), you can also set it dynamically, by specifying an elisp expression which evaluates to the tangle setting.

This is quite useful together with tags. Here’s a function which sets the argument based on which tags are currently set in the file:
