This file contains some examples of how to accomplish certain things using DTL.

1) Decode PHP-style foo[bar][baz][bat] keys into nested data structures:
    Input data:
    {
        "associate[name]": "Sand Creek, Inc. (136)",
        "associate[number]": "15-0202",
        "associate[crop][name]": "Wheat, hard red winter (Triticum aestivum) - Byrd",
        "associate[crop][number]": "R14-1-136",
        "associate[crop][lot_number]": "14-136C",
        "county": "Kiowa",
        "seed_class": "registered",
        "item[0]": 0.99,
        "item[1]": 0.0072,
        "item[2]": 0,
        "item[3]": 0.9928,
        "weed_result": 0
    }

    Transform:
    {
        "out": "(: unflatten({map($. 'handle_brackets')}) :)",
        "handle_brackets": "(: [ ($index =~ s/'(\\\\]?\\\\[)'/'\\.'/g) =~ s/'\\]$'/''/ $item ] :)"   
    }
