Why does `.name(str)` require a `'static` lifetime string?

[demmerichs]

I want to add names to predicates I construct inside a loop, e.g.

use predicates::{prelude::*, BoxPredicate};

fn test_predicates() {
    let gt = vec![1, 2, 3];
    let mut predicate: BoxPredicate<str> = BoxPredicate::new(predicate::always());
    for g in gt {
        let name = format!("{}", g);
        predicate = BoxPredicate::new(predicate.and(predicate::never().name(&name)));
    }
    assert!(predicate.eval("Hello World!"));
}

I expected to see this happen: Allow me to pass Strings, or &str which get cloned inside the naming.

Instead this happened: Compile Error:

   |
8  |         let name = format!("{}", g);
   |             ---- binding `name` declared here
9  |         predicate = BoxPredicate::new(predicate.and(predicate::never().name(&name)));
   |                                                     ------------------------^^^^^-
   |                                                     |                       |
   |                                                     |                       borrowed value does not live long enough
   |                                                     argument requires that `name` is borrowed for `'static`
10 |     }
   |     - `name` dropped here while still borrowed

Reason: a lot of the features were developed for basic test cases, like with assert_cmd and assert_fs where dynamic data isn't as needed.

That doesn't mean it can't change though it would involve a breaking change.
