That's a better explanation right there than in the docs.  I was only 
saying how I think it should work, how it *does* work is only now made 
clear.

Ah!  so the full path information isn't even retained anywhere. Once 
it's in memory it doesn't matter.  But if I do this:

2 /aWorking/Zsh/Source/Wk 5 $ . $(realpath ./rap)

... whence shows me this:

rap is a shell function from /aWorking/Zsh/Source/Wk/rap

... because the full path is actually available at the time of 
sourcing.  There is always a way.
