I am told that Niklaus Wirth only allowed for compiler optimizations in which the optimizations paid for themselves in speed, when compiling the compiler. This is said to be the reason for the Oberon compiler's speed. [1] I have only skimmed Dybvig's paper on Chez Scheme, but I think it would be interesting to compare the speed of a compiler that uses Dybvig's nanopass framework [2], and a compiler optimized according to Wirth (using only a single pass).
