//! Regression test for [Using the result of an assignment expression results in an LLVM assert
//! #483][issue-483]. This test checks that assignment expressions produce a unit type, and is
//! properly lowered to LLVM IR such that it does not trigger an LLVM assertion. This test was added
//! *really* early, back in 2011.
//!
