[New extension] Project lpp: Introduces OOP to Scratch!

[FurryR]

🐺 lpp

A high-level programming language based on Scratch developed by @FurryR.

🛠️ Features ✅ Use lambda functions (functional programming) like @LilyMakesThings's inline but more powerful and works fine on compiler mode. ✅ Make complex objects like class instances. ✅ Visual debugger & traceback. ✅ Direct JSON construction without JSON.parse in Scratch. ✅ Exceptions & try-catch system. ✅ Use your favorite Promise and stackless coroutine (yield, yield*, await). ✅ Fully compatible with original Scratch (using Eureka), even with early versions (before commit 39b18fe by @mzgoddard, Apr 12, 2019). ✅ zh-cn, ja-jp (WIP) and en-us translation + en-us documentation. 🤖 See more detail & try out demo
