+//! Test that an alias of derive_builder is valid in #[builder(crate = "...")]
+//!
+//! This test is imperfect, as it still passes without setting `crate = "..."`.
+//! This is likely because `derive_builder` is automatically present in 2018
+//! without needing the extern crate line.
+//!
+//! The test will fail if an incorrect alias is used, so it adds limited value.
