I posted an earlier version here before as a learning project. Since then I have been moving it toward a more practical direction: v0.2.0 adds a C embedding API and builds the runtime as libpico. A host program can now create a VM, evaluate PiCo code, register native C functions, call PiCo functions from C, capture output/errors, and prevent scripts from terminating the host process.

It is a small toy language. The current public value API is intentionally limited to null, bool, and number.

That's cool. Did you compare performance with the PUC Lua VM versions (which are register based as well)? Personally, I find the Are-we-fast-yet suite very useful and usually migrate the suite to my languages to compare the implementations (see e.g. https://github.com/rochus-keller/are-we-fast-yet/).
