Sorry, but it seemed like you were trolling. Guile is not a one man show. I have been active in the Guile community for 5 years now, so I know. I will admit that the bus factor in the compiler portion of the code is high, driven almost exclusively by Andy, but he has done a significant amount of writing about how the compiler works and even listed several other improvements that can be done in an effort to get more people involved. I have no experience with compiler hacking and yet I was able to implement an optimization and get it into the 2.2 release. The commit history alone isn't enough to understand the group of people that push Guile forward.
