Aha, yes, that property even has a name - something
that can be placed anywhere and still produce the same
result, even if invoked repeatedly...?
How common this pitfall is in Lisp one has to wonder
though... do you have an example? I never had a
problem, but perhaps that is because I only recently
started to byte-compile all my code.
Not that I experienced anything, actually, save for the
warning messages on compilation that perhaps served to
clean up the code.
And the system feels a tiny bit faster (perhaps my
imagination).
