Just so. While portable code is more important, I don't think we should
discount non-protable code completely. And I don't think we should force
people to write only portable code. Besides, using EQ in a portable way
is generally easier than using declarations.
I realize that CL has gone a different way with the generic arithmetic
functions, but the two cases are not identical. If necessary, I suppose
a more elaborate justification for EQ could be attempted, but is there any
great harm to keeping EQ?
