Okay. I'll look into that. Emacs is more general, because it will be
installed on more systems. But when Common Lisp is a better option, I
should maybe go for it.

By the way. I have been looking into Common Lisp and I understood that
the following is correct:
    (list a: 1)
But I get:
#<IO TERMINAL-STREAM>>: er is geen package met naam "A"
    Mogelijkheden om opnieuw te beginnen:
    ABORT          :R1      ABORT
    ABORT          :R2      ABORT
    ABORT          :R3      ABORT
What is going wrong here?
On the system is the version: GNU CLISP 2.39. So maybe I should update.

I thought about this, but the functionality is run from a bash-script. I
like to have everything in one file, but maybe I should work with
several files.
