What Hacker News says
2 sourcesThere's a reason why a lot of programming language papers use formal math notation, because it's a lot more concise to express the entire typing rules of your language in a dozen or so inference rules rather than a more convoluted implementation.[0]
Formulog looks like it could potentially replace that math notation for something as rigorous yet executable.
On the other hand, denotational semantics are usually straightforward enough to be implemented by reading off the math. As an example, it was quite easy for me to translate Scheme's semantics to code.[1]
I hope it gets reimplemented in a functional language as well, Formulog's current implementation is in Java[2] which might not be ideal for reducing implementation bugs.
