Confusing error message with colliding struct fn and struct member names

[Sahnvour]

I was surprised to find that this snippet

const Foo = struct {
    bar: u32,

    pub fn bar(self: *Foo) u32 {
        return self.bar;
    }
};

test "bar" {
    var b = Foo{ .bar = 0 };
    _ = b.bar();
}

gives the following error

$ zig test typeIsNotAFunction.zig
typeIsNotAFunction.zig:11:10: error: type 'u32' not a function
    _ = b.bar();
         ^

I think Zig should first warn of an identifier clash, instead of choosing the struct member, and trying to use its type (??).
