Hi, I wanted to share with the mailing list members here details about the project I've been working on: https://github.com/jeffreyhorner/R-Array-Hash This is a re-implementation of R's hashed environments, the global variable cache, the global string cache and symbol table with cache-conscious array hash tables. The results are quite encouraging. However, the implementation is a big
