Type inference fails in ark-gl

[felixangell]

Specifically here:

pub func (g: ^Game) render() {
    mut i := uint(0);
    for i < g.entities.getLength() {
        entity: ^mut entity::Entity = g.entities.get(i);
        match entity {
            some(e) => {
                e.render();
            },
        }
        i += 1;
    }
}

I get this error:

error: [game:45:5] Unable to infer type of member `render` on type `$104`
                e.render();
                ^
