Because seriously, why is `type` the only approximate keyword when it just acts like a #define? How about an actual type definition?

typedef.rs

macro_rules! typedef {
    ($name:ident, $type:ty) => {
        #[derive(Debug, Clone)]
        struct $name($type);
        impl From<$type> for $name {
            fn from(value: $type) -> Self {
                $name(value)
            }
        }

        impl From<$name> for $type {
            fn from(value: $name) -> Self {
                value.0
            }
        }
    };
}
