You'll need to keep in mind that some operations cause the optree to alter itself at runtime. First on my mind is the /o regex modifier (and maybe that's it for core perl). Maybe also tricks with B::Generate to alter the optree at "runtime" (considering that BEGIN, CHECK, INIT, runtime, and eval string are all different runtimes).
