If I recall correctly, someone with the best intentions attempted to write a clear, object-oriented (but still C/C++ based) regex engine to replace the existing highly hairy code. As a result it missed fitting in the cache, and ended up being like two orders of magnitude slower. Not arguing for premature optimization, but anyone thinking about regex might want to look ahead (get it?) to the end game where regex pretty much has to be within .2x of its current speed. F.
