The "right" way to do this would be to use the GHC API.
(Actually - can you read kind information from the GHC API?
I'm not sure.) That would guarantee that your program
and the compiler will agree about kind inference.
So I view this package as similar to the "haskell-src-exts"
package: a lightweight alternative to the GHC API for
a certain task, where you are willing to sacrifice the
100% guarantee of compiler compatibility.
Of course, we hope that the package will in fact be completely
compatible with the both the compiler and the Report.
And like "haskell-src-exts", ongoing testing and debugging of
compatibility could have the additional benefit of improving
both compiler and the Report. :)
