Description
Hey HN! I built Gojju, a programming language that cherry-picks my favorite features from 5 languages:- Python: List comprehensions, slicing- Ruby: #{interpolation}, postfix if, blocks- Haskell: |> pipe operator, lambdas \x -> x+1, Maybe/Either- Perl: unless/until, regex literals- JavaScript: Arrow functions =>, spread ...Example: [1, 2, 3, 4, 5] |> filter(\x -> x % 2 == 0) |> map(\x -> x * 2) |> sum Install: `pip install gojju`The name "Gojju" (ಗೊಜ್ಜು) means "essence" or "secret ingredient" in Kannada.Would love feedback on the syntax choices!

Could you build this?
Partial Toy interpreters can be scaffolded by LLMs, but building a robust multi-paradigm programming language with consistent AST semantics, type handling, and runtime execution requires dedicated compiler engineering.
What it would actually take: Likely built with a parser generator (or handwritten recursive descent parser) feeding an AST interpreter or bytecode VM written in Go, Rust, or Python. The hard part is reconciling disparate semantic models (pipes, blocks, list comprehensions, postfix syntax) into a sound grammar and error-free execution environment, requiring formal programming language design and compiler development skills.

Nobody's really built a dev tools tool for Sales yet.
