P++ is a new experimental programming language designed to bridge the gap between ease of use and performance.
Key features include Interpreter Mode for fast iteration and debugging, LLVM Compiler Mode for JIT/AOT execution and performance, a new REPL shell, and a simple syntax with an extensible architecture.
Developers can switch between interpreted and compiled modes easily, allowing for fast prototyping and efficient execution when needed.
The language supports a variety of features like inline assembly, memory management, and class definitions, aiming to combine the strengths of languages like Python and C++.
