Sorry, but I don't understand... Could you give me some example?

So, if I continuously want to add and remove functions within one shell
(running hypothetically forever), do I have to 'manually' delete those empty
left-behind files? --- that is, not only use
fn name_that_I _don't_need
but also
rm /env/'fn#name_that_I _don't_need' ?

(I was playing with this to have a prompt that reflects the last part of my
current directory. Following the example of setting fn term% { $*} I,
whenever I change a directory, define a similar function with an appropriate
name. When I change the directory again I do the same for the new one, but
also want to get rid of the old one... -- actually in the opposite order.)
