Can't specify a default for a string reference attribute

[Nemo157]

#[derive(PromAttire)]
struct Attributes<'a> {
    #[attire(default = "bar")]
    foo: &'a str,
}

Defaults use FromStr only, so you get errors like

error[E0277]: the trait bound `str: std::str::FromStr` is not satisfied                                                                                                    --> <anon>:9:10

  |          ^^^^^^^^^^ the trait `std::str::FromStr` is not implemented for `str`

Probably need to use something like prom_attire_impl::expand::match_parse for parsing the provided default.
