`syn::parse_item` fails to parse enum with custom values

Sorry for the slow response - I am on vacation this week without internet access. This will be my highest priority when I get back on Friday, unless someone has a PR ready by then.

I fixed this in 0.6.0. Variants now have an optional discriminant field so your example looks like this:

enum Foo {
    A = 1,
    B = 2,
    C
}

MacroInput {
    ident: "Foo".into(),
    vis: Visibility::Inherited,
    attrs: vec![],
    generics: Generics::default(),
    body: Body::Enum(vec![
        Variant {
            ident: "A".into(),
            attrs: vec![],
            data: VariantData::Unit,
            discriminant: Some(Discriminant {
                value: 1,
                ty: IntTy::Unsuffixed,
            }),
        },
        Variant {
            ident: "B".into(),
            attrs: vec![],
            data: VariantData::Unit,
            discriminant: Some(Discriminant {
                value: 2,
                ty: IntTy::Unsuffixed,
            }),
        },
        Variant {
            ident: "C".into(),
            attrs: vec![],
            data: VariantData::Unit,
            discriminant: None,
        },
    ]),
}
