I think sometimes that there's a niche for an alternative syntax for Rust that is generally more verbose (keywords instead of punctuation etc), and which specifically makes this behavior explicit. In other words, for every argument of every call you'd have to write "move" or "copy" and similarly with assignments etc.
RustRover recently added visual indication of the borrowing process within a block of code, which is kind of nice. I think for now it only shows for some cases and only when there's an error? but still you get a highlight of where the borrow happened so you can walk back to it and figure out how to fix it without having the parse through the compile error.
I suspect they'll eventually get a fast and live indicator to the user of where all the references are "going" as they type.
