Description of the bug

Getting an unexpected error for a jq filter.

error: Error parsing jq filter: found end of input

Reproducing the issue

I am trying to do something like this, which feels like it should work (I want to iterate over every other CPU core)

(for core in {jq("${arraylength(EWW_CPU.cores)}", "[range(0; .; 2)]")}

The error highlights the r in range as the problem.

Expected behaviour

As tested with both jq and jaq, the result should be an array rather than a parsing error.
