If you want to have fun exploring how compilers work, in your spare time after a hard day working in C++, what better way than to reimplement a language you know? On the other hand, my projects in this vein are C++ projects but they implement functional languages or Scheme. I have implemented one parser that creates a syntax tree from a simple equational language, and several interpretive backends, such as SKI-combinator-based graph reduction and a TIM-based interpreter. I do care about the speed of the compilers I use for production code, but not for this work. The Scheme compiler I wrote was written to run on my own Scheme interpreter which was written in C++. The reason I think most hobby compilers I know of don't go the way I've gone is that it takes tons and tons of research to find out how functional languages are implemented, and the Appel books are a bit daunting, too.
