Inner item declared by nested macro not resolved

[flodiebold]

macro_rules! inner_declare {
    ($ident:ident) => {
        static $ident: u32 = 0;
    };
}
macro_rules! declare {
    ($ident:ident) => {
        inner_declare!($ident);
    };
}

fn foo() {
    declare!(bar);
    bar;
  //^ u32
}

This test fails; bar isn't resolved. Changing declare! to inner_declare! makes it work.
