[QA] Nested `[` is officially support?

[fredppm]

Hello

I was trying to figure out if the nested brackets is officially support or may be a bug feature.

My may sample

I want to sum all values from the array of objects named totals and filter it when only this object has the Id with CustomTax or Tax
So this query works for me
(totals[id in ["CustomTax", "Tax"]].value ? $number($sum(totals[id in ["CustomTax", "Tax"]].value)) : undefined)

But using the try page the syntax highlight appear to be bugged

I didn't find any warnings in the docs about this nested operations so I want just to confirm if the query interpretation officially handling this inception .
Thank

That expression has no syntax errors for me in the exerciser (i.e. the try page).

BTW, this expression is effectively the same (I'm not sure of your input data):

$sum(totals[id in ["CustomTax", "Tax"]].value)

I suspect @fredppm doesn't like the colours in the exerciser.
There is an issue open for this: jsonata-js/jsonata-exerciser#18
Closing this one.
