[springcomp]

This discussion has been started to list topics that could be included in a next version of JMESPath. This is a good place to discuss proposals and new features.

Features with a ✅ check-mark are available or prototyped in most JMESPath Community implementations already.
Features with a 📃 symbol have a reasonable first JEP draft. Please, share your feedback.

Here are the topics we currently have:

• Structural Manipulations
  • Recursive Tree Traversal 📃
• Functional Programming
  • Obsolete JEP-11 in favor of a newly proposed let-expression. ✅
  • JEP-11a Lexical scope ✅
  • reduce function
• Functions
  • The date() function.
  • The indices() and range() functions. 📃
• Miscellaneous Topics
  • Ordering Arrays and Strings. 📃
  • Third-Party Functions 📃
  • JEP-20 Compact-style for multi-select-hash 📃
• JEP-21 Ternary Conditional Expression ✅

Please, feel free to to advocate for yet more of the features we had been brainstorming last year but did not make it to the current release.

The date() function is a good idea 👍 👍

Recursive tree traversal is undeniably a valuable feature. Really looking forward to it.
