Sounds similar to the evaluation model of the Nix expression language (the pure functional programming language used by the Nix package manager). It caches evaluation results, which (a) avoids re-computing identical expressions, and (b) allows some infinite loops to be detected.

Thanks for bringing that up! I suspected that nix did that, but wasn't sure. This language is also a "task runner" (being used for build systems mainly), so it's not surprising that it behaves like nix does.
