-// Check that closures do not implement `Clone` if their environment is not `Clone`.
+//! Test that closures only implement `Clone` if all captured values implement `Clone`.
+//!
+//! When a closure captures variables from its environment, it can only be cloned
+//! if all those captured variables are cloneable. This test makes sure the compiler
+//! properly rejects attempts to clone closures that capture non-Clone types.
