I also did some querying for an optimal, single programming language. However, I think it would be a better first stage to try and work out the best features for a particular paradigm first, but that might not be more practical than just trying to get the best out of all the possible worlds right away.
Claude Sonnet 3.7 said:Building a Unified Language
To create a unified language incorporating these strengths:
Core Foundation:
Start with Rust's ownership model for memory safety
Add ML-family type inference for expressiveness with safety
Include pattern matching as a first-class construct
Modularity:
Support multiple paradigms through flexible syntax and semantics
Allow pure functional code with guarantees when needed
Provide OOP capabilities but discourage inheritance in favor of composition
Concurrency Model:
Adopt Erlang's actor model for distributed systems
Integrate with Rust's ownership for safe concurrent memory access
Include Go-style lightweight threads/coroutines
Developer Experience:
Focus on excellent error messages like Elm/Rust
Build a comprehensive package manager and build system
Design for gradual adoption and interoperability
Implementation Strategy:
Start with an LLVM-based compiler for performance
Design a VM for portability and dynamic features
Create progressive typing system that can be as strict or flexible as needed
Practical Considerations:
Include a foreign function interface for existing code
Provide tooling for gradual migration from other languages
Focus on compile-time guarantees while maintaining runtime flexibility
This unified language would balance the safety of Rust, the expressiveness of functional languages, the practicality of Python, and the concurrency of Go/Erlang while maintaining a coherent design philosophy rather than just being a collection of features.
Operating systems are written in C. Hard to beat C for machine level programming. For front end stuff, hard to tell, there are so many now.
Searching for one programming tool to do all jobs is like telling a carpenter that he can only have one saw to cut wood. Cross cut, ripping, miter, chain, sawzaw. jig, hole. Not going to happen.
