List which definitions changed in a commit

Stream: Is there code for X?

[Joe Hendrix]

On Std, there's somewhat frequently commits that move definitions around. Are there any scripts to validate that definitions did not get dropped in the process?

I think it'd be pretty straightforward to write a script that prints the environment out in an order sorted by name, so I could diff before and after, but I wanted to see if it already exists.

I think leaff (search on zulip) should work for this
