Could you build this?
No Designing and implementing an entire novel programming language, compiler, runtime, and ecosystem requires deep, multi-year computer science expertise in compiler architecture and language design.
What it would actually take: Developing a real programming language requires lexer/parser architecture (e.g., using ANTLR or custom recursive descent), an AST specification, type inference/checking systems, an intermediate representation (IR), and a backend code generator (LLVM or bytecode VM). It also requires runtime memory management, standard libraries, and debugger tooling. This demands specialized compilers and systems engineering expertise, typically taking years of iterative development.
Discussion
6 comments analyzed.
Concerns raised: Language brittleness needs hardening, Developer experience at ecosystem scale uncertain, Single language for all use cases unproven

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
