Project description:
"I have sketched out a small, Hinglish-flavoured programming language and now need a working compiler built as soon as possible. The language should feel conversational—keywords and error messages may mix Hindi and English—yet it must follow a functional paradigm. At minimum the compiler must understand basic arithmetic expressions, variable declarations and pattern-free control-flow statements such as if-else and simple loops.

You are free to choose the tech stack that feels most productive to you—ANTLR, Flex/Bison, LLVM, Python’s ply, or any other modern compiler-construction toolkit—so long as the final artefact can take a plain-text source file and either run it directly or emit an intermediate form that executes. I care more about a clean pipeline (lexing, parsing, semantic checks, code generation or interpretation) than fancy optimisations.

Deliverables
• Source code with build/run instructions
• A small standard library or runtime stub, if required
• Sample Hinglish programs exercising arithmetic, variable bindings and control flow, along with their expected output
• Brief documentation explaining language grammar, supported keywords and how to extend it further

Because I need this ASAP, show me a runnable skeleton—or at least the lexer + parser—within the first few days, then iterate quickly to full functionality. If this prototype behaves well, we can explore extra features in a follow-up phase." (client-provided description)
