Keep in mind the date (and origin) of the paper -- expect some vocabulary mismatches. In particular: "run M, in a general form, with unknown values of variables" would probably be called abstract interpretation today. (I'm only fudging because I haven't read the rest yet myself. :) Edit to add something I forgot to mention, but should: There's a(t least one) useful PDF of slides in the repository from the originally linked project. I did go through that, in something of a hurry -- it walked through the rewriting of a naive function to append 3 lists [ app3(a,b,c) = app2(app2(a,b),c) ]into one that executes with a single pass.
