Indeed, that is just the way it has been for a long time. I did try
switching to the `eval-when-compile' part, but this doesn't work. EIEIO
has functions which create types with deftype, and uses typep. If I
wrap the require of cl as above, then sources creating classes can't
find the typep symbol.
It could be I am using deftype and typep in some inconsistent way. If
someone is interested in pointing out the correct way to do these
things, I'd appreciate it.
You can look at EIEIO w/out getting the whole CEDET suite here:
