I remeber the orinial discussion that reader macros do nothing more than
slow down compilation. Not to mention the confusions.

I liked the idea of

(with-current-readtable (xyz)
    ...)

i think franz was doing this, and they added the case of symbols.

At readtime they can be usefull. When I'm done using the reader macro I
reinstall the old one.
