pub fn assert_is_exclusive_system<Params, SystemType>(
    _sys: impl IntoExclusiveSystem<Params, SystemType>
)

Ensure that a given function is an exclusive system

This should be used when writing doc examples, to confirm that systems used in an example are valid exclusive systems

Passing assert

fn an_exclusive_system(_world: &mut World) {}

assert_is_exclusive_system(an_exclusive_system);

Failing assert

fn not_an_exclusive_system(_world: &mut World, number: f32) {}

assert_is_exclusive_system(not_an_exclusive_system);
