Right now, I there is a problem with lisp, the resulting condition is not very
helpful, unless I go into backtrace. In some environments, however, I can't do such a thing, so I am left with (if printed readably):

Odd number of keys

Now when I write it's usually new code which is wrong so I find these
quite easily, but I mean generally, this is not much helpful.

that is all I get. Is there a better way to print conditions, maybe
include some localization for the error or something?

Thanks for any ideas.
