That's pretty awesome. The new CTFE engine release will soon
rival Tesla Model 3 in terms of interest raised :o).
In addition to artificial corpora like the above, I suggest
comparing against real-world code - starting with simpler
things such as bitfields instantiations.

That will not work currently.
Since function and methods calls are still "in the works".
They will require another restructuring as well.
Therefore artificial tests are the best I can do to gunge
performance.
