I stumbled across the original "Lambda the Ultimate" papers by Sussman and Steele and the effect produced from reading them is profound. It is as if someone suddenly lit a huge halogen floodlight into an enormous black cavern. :)
More seriously, several topics such as continuations, continuation-passing-style (CPS) and the compilation of functional languages make about 100 times more sense now. Hopefully I can get back on track and read what I was *supposed* to be reading before the research meeting on Wednesday..
