We can't make Qnil pure, because its plist can be written.
(It can also be defined as a function, though that would be an
ugly thing to do.)
However, we could make Qunbound pure, since it is just a token, not a
real symbol. It is used only for EQ comparisons at C level.
Would someone like to try that?
