I did use the example of long run of module names, and I do take your point about `use` (though I have to sometimes read the very top of a file too!)...but the same applies to a lesser extent to the "last mile" module (e.g. `String::from`, `Vec::new`) which will be seen throughout any rust code.

Interestingly, from the zig documentation:

    Zig source files are implicitly structs, with a name equal to the file's basename with the extension truncated. @import returns the struct type corresponding to the file.

This means that there isn't really any difference between accessing a struct field and accessing something in module...the module is also a kind of struct (and rust, as in zig, differentiating struct field access vs function invocation is possible because of the parens in the latter).
