                                  Hello! I'm MiloIgnis, a part-time PhD student studing programming languages and compilers.
                                  My current project is making a functional language based on Vau-calculus (inspired by John Shutt's work) practial via partial evlauation and some clever compilation techniques.
                                  That project, Kraken, is <a href="https://kraken-lang.org/">here</a>.
