I did use the original for the prototype of macholib! Then I wrote a 
version in pure python to eliminate the compiler dependency and ended 
up adding way more features than I actually needed (variable length 
nested structures and stuff like that). Eventually, I scaled it back 
to this so that it was easier to maintain and so that I could make some 
performance optimizations (well as many as you can make with the struct 
module).
