So I see all those borrow '&' sigils littering almost every function

to eye-soreness Rust syntax causes. Since '&' is so popular, couldn't
Rust just make it a default?
For instance, what if the following rule were be adopted: "All unadorned
function parameters are implicitly assumed to be passed by
borrow-reference"? Now, of course, this be inefficient for small types
like int, but that could be dealt with by specifying that types less
than N bytes in size (N perhaps being platform-dependent), are passed
by-value, except if mutable, or if adorned by lifetime of another parameter.
Ok, this is not a serious proposal, because I am probably missing a lot
of corner cases, but I would like to hear why this wouldn't work.
We tried this once ("modes"), and it was very confusing, especially when
generics were involved.
