Henry Baker's "Cheney on the M.T.A." paper (which is the basis for the stuff described here) is very nice. There's a collection of Baker's research papers here:

http://www.pipeline.com/~hbaker1/

which includes the "Cheney on the M.T.A." paper (http://www.pipeline.com/~hbaker1/CheneyMTA.html) and a bunch of other interesting things (mostly with a lispy flavour). A few specific examples:

http://www.pipeline.com/~hbaker1/Prag-Parse.html -- a nice technique (not invented by Baker) for simple parsing tasks, and a neat Lisp implementation.

http://www.pipeline.com/~hbaker1/LazyAlloc.html -- you might notice that the "M.T.A." paper is subtitled "CONS should not CONS its arguments, part II"; this is the original "CONS should not CONS its arguments" and is also about allocating things on the stack that you might not expect to be stack-allocatable.

http://www.pipeline.com/~hbaker1/Use1Var.html -- "use-once" variables (related to "linear logic", which is not Baker's creation), not a million miles from C++'s auto_ptr/unique_ptr but Baker was advocating this stuff as early as 1993.

And some other interesting things due to people other than Baker, such as a copy of the famous HAKMEM (http://www.pipeline.com/~hbaker1/hakmem/hakmem.html).
