I have never written a Zig program, I've just browsed the specification. I do admire the energy and enthusiasm of its creators. The fast compiles of it are well done.

Mostly what I think is the syntax is more complex with less utility than the equivalent D syntax. For example, the use of the 'comptime' keyword is not necessary. For another, the import declaration is overly complex.

I don't know enough about Zig to make informed suggestions on evolving it. D has borrowed stuff from many languages, but I don't recall suggestions in the D forums of a Zig feature that should be added to D, though I might have missed it.
