Well, this quickly became a pain.

This will be near impossible without importing thousands of lines of code from the compiler. Swift interop is already probably far too difficult to achieve without writing C++, and in Joe's own words:

"If you're writing code in C++ already then definitely just using the headers or MetadataReader as is will keep you better in sync with future additions to the runtime."

Another option to consider is libSwiftRemoteMirror.

This commit leaves the project in an incomplete and broken state.
