It doesn't really matter if Walter knew about what Zig was doing or not. It was a good idea and it's a good addition to D at the end of the day. | |||

Does it really matter? The history of programming languages is interesting in itself and it's good to acknowledge those making progress. It's also good to adopt/adapt the pioneering work of others. I'd also note that many programmers come to previously discovered good ideas independently. OTOH, I think we've all known people who have made false claims in this area. I'd rather associate with those who don't. So, yes, I think it matters but I don't see it as a big problem within the D community itself. | |||

CTFE works just fine on ImportC code !!
I use it to speed up tests in the ImportC test suite. No need to build an executable for many of the semantic tests.
