I say this as someone who enjoys reading Rust more than Haskell or Elm -- that looks like a really bad idea for aesthetic reasons anyway. I mean if you want the syntax to look like Zig or Rust, perhaps go all the way there instead of making a kind of a mutant hybrid like this. Syntax is superficial and the semantics actually matter, but that doesn't mean the syntax can be just anything.

Is there some deeper technical reason for making such changes?
