3. short_maps

   2 1 76 - Elixir

   Discontinued ⚠️Retired⚠️ library that provided a ~m sigil for ES6-like map destructuring in Elixir.

   This was done previously with the `short_maps` library, which the author—a member of the Elixir core team—eventually retired and archived due to regrets from the undesirable impacts on clarity.

   2. at the same time, being a language feature it should be simple - es6_maps works only with atom keys and has no extra features over the key expansion.

   Point 1 is additionally reinforced by how easy it was to introduce to the compiler - I’m injecting just 9 lines of simple code, while parser and lexer already accept short-form maps without modifications.

5. destructure

   4 1 110 - Elixir

   Javascript-style destructuring for Elixir

   

   I've been using Destucture [1] for a few years. It's an interesting compromise that works for atom and string keys because it's explicit, kind of like the sigil approach. Though this seems way more streamlined, especially as someone who uses JS for front-end apps.
