CMUCL does this to reduce the size of FASL files (and as a side effect, the size of images that it generates). CLtS allows literal objects such as your quoted lists to be coalesced by the file compiler; see section 3.2.4.4 "Additional Constraints on Externalizable Objects". The specification does not allow this for interactive compilation (via COMPILE), and CMUCL conforms to this requirement (since recently, anyway). <http://www.ai.mit.edu/projects/iiip/doc/CommonLISP/HyperSpec/Body/sec_3-2-4-4.html> -- Eric Marsden <URL:http://www.laas.fr/~emarsden/>
