Shouldn't this error be considered a compiler-bug? The Add trait says '&' for
rhs after all:
fn add(&self, rhs: &RHS) -> Result;

This is https://github.com/mozilla/rust/issues/8895 . I believe it is
caused by the implementation details of the overloaded-operator
desugaring (a + b is equivalent to `a.add(&b)`, so auto-deref allows for
`a: &T` with `b: T`), I personally think the more sensible resolution
would be for `p + n` to be disallowed as well as `n + p`.
