That didn't quite work, as exists is not a recognized function
Of course! For me it was obvious that I only wrote pseudo code. Sorry, that I did not express this more clearly. Instead of exists: (fboundp SYMBOL) ? (symbol-value SYMBOL) throws an error if not existing ...
The idea is to create a semaphore that shows that you've already done this initialisation, that doing it again can be prevented when the semaphore is queried – common to a few programming languages. I am no Lisp programmer, so I cannot tell what the right approach is. Could be it's best to just check whether the variable already contains (matches) your addition?
