I understand that reading the plain source code is more painful then reading a paper.

There are many different trade-offs between a paper and the current repository with source code. For me the biggest argument was that EventReduce is a performance optimization. So to be sure if it really works and is faster, you always need an implementation since you cannot predict the performance from a paper.

Because I did not have time for both, I only created the repository with the implementation. Maybe a paper will be published afterwards.
