A Program is a - "dependently typed" - "effectful" - "HOTT (Higher Observational Type Theory) aware" programming language. main := #print #"hello, world!"; Type system as preceding computation, Compilation as proceeding computation, Execution as effect aware interaction. Thep source files are compiled intoa artifact files. Artifact files are to be trans-piled into other programming languages like - C programming language - Verilog HDL - CUDA C so, "A" is a programming language for all programs.

Could you build this?

No Designing and implementing a dependently typed programming language with Higher Observational Type Theory (HOTT) and algebraic effect handling requires deep academic theoretical computer science and advanced compiler engineering expertise.

What it would actually take: Requires deep expertise in type theory, homotopy type theory, category theory, and compiler construction, typically implemented in Haskell, OCaml, or Rust. Building it demands implementing bidirectional type checking, normalization-by-evaluation, proof-search/unification algorithms, and a sound execution runtime for effect handlers.
