Aidan, would you please take the time to explain why this DTRTs?  A
good place would be as a comment in the code, and you should feel free
to point that out to a reviewer (probably me ;-) who asks for more
explanation.

The reason in this case is that byte compiler expertise is now a rare
commodity.  Even a small thing like explaining why that
print-gensym-alist interferes with byte compilation would help raise
consciousness (speaking for myself, of course, and possibly others).
