It's noticeable that there are a lot of differences, and some things seem to have been deliberately made different (even if they are in essence very similar and only syntactically different), so for me it looks a bit odd that most references to Rust on his blog nowadays are of adversarial nature (ie, "look how better we are than Rust").
Last, but not least, it also doesn't help with the big picture that the one continuously posting links about Zig here is just self-promoting their own creation...
Anyway, just my $0.02
