Conditions and Loops about mutton HOT 3 OPEN

I'm actually thinking I could try and do some sort of inference based on the tokens (if/for) at the evaluation step w/ some sort of recursive call back into the engine.

Interesting thoughts! Thanks for opening up the conversation. I haven't given this much thought, but I'm wondering if it's possible to solve this by calling back into mutton as you suggested. Mutton is designed to be low-level and generic. Basically only for simple templates. There could be value in adding more mustache-like features though. The reason why mustache/handlebars did not work for my original use case was because they did not allow for plugging in custom evaluation. Mustache and Handlebars are opinionated in that way (not a bad thing, just didn't work for what I need it for).

I see that jsonata supports $map and $join. Perhaps you could do something like:

{{
  $join($map(names, function($v, $i, $a) {
    $v & ' is a fun name'
  }), '\n')
}}

What are your thoughts?

100% - Mutton is great because it is un-opinionated about those type of things.

I wrote a similar expression as a prototype but felt it was just wayyyy too complex for the majority of users. I think striking a balance between super flexible and user friendly is a tough balance. At the same time, I feel like those are pretty typical asks of any engine like this so a boilerplate answer or hook might be the best approach.
