This is interesting if only because it is from Chris Lattner who created LLVM, Clang, and Swift — now bringing his attention to the Python world.

Existing Python code should work unmodified, but it also adds features that enable performant low-level programming—like “fn” for creating typed, compiled functions and “struct” for memory-optimized alternatives to classes.
