I have to remember it. :)

Yes, if I am not careful. :)

In practice there are usually only a few thorns in my 'working set',

If I wanted to be fancier, I could have each thorn for which I keep
multiple versions announce itself via a unique banner printed on startup
(maybe just the absolute pathname from getcwd(3)).
