Transform #'princ to #'write-sequence at compile time if appropriate. lisp/ChangeLog addition: 2013-12-22 Aidan Kehoe <kehoea@parhasard.net> * cl-macs.el: * cl-macs.el (princ): New compiler macro. Transform #'princ to #'write-sequence if we can determine at compile time that it is being passed a string. Initialising the printer is expensive enough, but much of our code took this approach because #'write-sequence wasn't available.
