Make-instance takes keyword arguments like this:
(make-instance 'class :key1 arg1 :key2 arg2 ...)
It could take ordinary symbols instead of keywords like this:
(make-instance 'class 'key1 arg1 'key2 arg2 ...)
I'm making an object-oriented system that has a similar syntax for
make-instance, and I have a choice about which way to do it. Does
anyone have any advice about the pros and cons of the two
alternatives? I see these:
Pros for first choice:
User doesn't have to mess with packages as much.
Cons against first choice:
If the keywords are the same as the names of slots, then forgetting
the package may create collisions.
