Isn't the same argument valid for lists? At least in the Emacs
backtrace, lists get shortened for display; I don't know if that's done
at the print level or at the display level. If it's at the display
level, a lot of cycles are wasted for large lists.
Basically I want to treat hashtables like lists as much as possible for
printing and reading, so print-readably would introduce inconsistency.
Otherwise I agree with your argument, I am just reluctant to make
hashtables an exception to the general print behavior.

Heh.

Great.
