You might want to clarify in the readme that the red X means non-goal. Until I read this comment I thought it was a goal that had not yet been implemented.

in the 14 hours since I wrote the comment you replied to, I moved an MRI C API from non-goal to goal [0]. :) The red X means the goal is not yet achieved.
However, it may be possible to use `rubysys` in rutie as a base for an MRI compatible API: https://github.com/artichoke/artichoke/issues/88
