The spec says very clearly that the standard readtable (which you may not modify) is *different* to the initial value of *readtable*, which is the "initial readtable", and which you may modify. Indeed I do not think there is any defined access at all to the standard readtable other than that (copy-readtable nil) will make a copy of it which you can then modify.  Whether or not something which is not programmer-accesible is immutable or not is kind of a moot point.

I have not checked the pprint dispatch case but I'm guessing it is the same.
