TurboWarp & forkphorus detector

Instructions

Read this entire text! It will answer all of your questions. This how to detect whether a project is running in a compiler like TurboWarp or forkphorus. We intend for this to be used to automatically enable laggy features in compilers without affecting normal Scratch or to suggest users to visit a link for a better experience, but ALWAYS allow users to run the project in normal Scratch anyways, even if it's really slow. Not everyone can access TurboWarp. https://turbowarp.org/414716080 https://forkphorus.github.io/#414716080 How it works: This is not a hacked block or a hidden block. This is an custom block argument reporter. You can create one with "add input (boolean)" while editing a custom block. Normally these always report 0 when you use them outside of a custom block, but some code in TurboWarp and forkphorus looks for this block and makes it report true instead. Other Scratch compilers are welcome to implement this. Thanks to @Executec for the idea of using boolean arguments.
