# Objective
- have errors in configure_set and configure_sets show the line number
of the user calling location rather than pointing to schedule.rs
- use display formatting for the errors
## Example Error Text
```text
// dependency loop
// before
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: DependencyLoop("A")', crates\bevy_ecs\src\schedule\schedule.rs:682:39
// after
thread 'main' panicked at 'System set `A` depends on itself.', examples/stress_tests/bevymark.rs:16:9
// hierarchy loop
// before
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: HierarchyLoop("A")', crates\bevy_ecs\src\schedule\schedule.rs:682:3
// after
thread 'main' panicked at 'System set `A` contains itself.', examples/stress_tests/bevymark.rs:16:9
// configuring a system type set
// before
thread 'main' panicked at 'configuring system type sets is not allowed', crates\bevy_ecs\src\schedule\config.rs:394:9
//after
thread 'main' panicked at 'configuring system type sets is not allowed', examples/stress_tests/bevymark.rs:16:9
```
Code to produce errors:
```rust
use bevy::prelude::*;
#[derive(SystemSet, Clone, Debug, PartialEq, Eq, Hash)]
enum TestSet {
A,
}
fn main() {
fn foo() {}
let mut app = App::empty();
// Hierarchy Loop
app.configure_set(Main, TestSet::A.in_set(TestSet::A));
// Dependency Loop
app.configure_set(Main, TestSet::A.after(TestSet::A));
// Configure System Type Set
app.configure_set(Main, foo.into_system_set());
}
```
