Echo v1.0.0

Echo 1.0.0

Stable release of Echo. Same language surface as 0.9.9 — no new syntax. Marks the completed 0.8 OOP spine and 0.9 ergonomics / stdlib series as the public 1.0 line.

Install: pipx install echolang (or pip install echolang)
CLI: prefer elang (also echolang, echo)
Docs: https://deekshith-poojary98.github.io/echo/

What’s in 1.0

• Typed scripting with runtime checks; abort + *Or failure model (no try / catch)
• Modules, first-class functions, const, destructuring, unions, switch
• Nominal class / interface (no inheritance): new { … }, methods, type methods, unbound methods, optional implements
• Ergonomics: compound assign on fields, priv, positional Point(3, 4), deep clone(), named format placeholders, get / set properties
• Scripting stdlib: mkdirAll / removeTree, regex builtins, UTC formatTime / parseTime, days / hours / minutes
• Analyzer: union narrowing in if type(x) == "…"
• CLI: run, REPL, check, test, fmt, lint + editor tasks

Still held

Inheritance, generics, packages, async, try / catch / Result / Option, HTTP builtins, LSP-as-product.
