Is there a JavaScript project that normalizes ECMAScript 5

Question

Is there a JavaScript project anywhere that focuses on native normalization ECMAScript 5 in common browsers?

For reference, normalizing a table like this: http://kangax.github.com/es5-compat-table/

I know about wrappers that adds some ES5 functionality, and falls back on native implementations if they exist. But I havent seen a project that focuses solely on native implementation and normalization. Any thoughts?

I'd pretty much recommend the ES5 Shim:
