Data-flow analysis is what I assume the author meant. Fancy word for "reasoning about behavior at a level higher than just a syntax node" (usually within a function or module, possibly within an entire program though) Both D and Rusts compilers do it, and I'm uncertain whether Zig's does but it may too.
