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?
