Some of the following are super obvious logically, but listing them for completeness.

• ✓ lvalue = lvalue / rvalue
• ✕ rvalue = lvalue / rvalue
• ✓ lvalue reference = lvalue
• ✕ lvalue reference = rvalue
• ✓ const lvalue reference = lvalue / rvalue
• ✓ rvalue reference = rvalue
• std::move(lvalue) will be rvalue
