2. In the top Menu bar press Test>Test BinaryReader to Span
Expected result: No error

Reproducible with: 2021.2.1f1, 2022.1.0a16
Could not test with: 2019.4.32f1 (Errors: "Library/PackageCache/com.unity.visualscripting@1.7.5/Editor/VisualScripting.Core/Reflection/TypeOptionTree.cs(55,21): error CS1525: Invalid expression term '='"), 2020.3.24f1 (Errors: "Assets/BinaryReaderSpan.cs(44,32): error CS0518: Predefined type 'System.Span`1' is not defined or imported")
