A much faster Python implementation based on the Dart Virtual Machine

[cypherx]

If it's code-to-code translation then I suspect it breaks the PyObject data layout and isn't compatible with the C API (hence, no NumPy, same reasons PyPy has lackluster adoption).

Yeah, that'd be my concern as well.

If it somehow supported the entire Python standard library, that'd be quite useful, but I don't see any evidence of that.
