> optimizations that the native version would incorporate

We shouldn't write stuff in native code for performance... We should write the compiler to detect these and output optimized code.

By "native version", I think that Cthulhu meant building "at" into the JS runtime, not writing "at" as a C extension and compiling it into native code.
