Suggest macro import

[pickfire]

I tried this code:

#[derive(Debug, Component, Clone, Copy)]
#[storage(VecStorage)]
pub struct Position {
    x: u8,
    y: u8,
    z: u8,
}

I expected to see this happen: compiler should suggest importing Component from specs (it is in Cargo.toml).

Instead, this happened: compiler say cannot find macro 'Component' but did not suggest importing it like other functions

error: cannot find derive macro `Component` in this scope
  --> src/main.rs:34:10
