Hello,

While using scriban, I can across a problem with ObjectToString where the escaping is incorrect.

Issue reproduction

var script = """[["a", "b"]] | array.each @(do; ret $0 | array.join("#"); end)""";

var context = new TemplateContext();
var result = Scriban.Template.Evaluate(script, context);
Console.WriteLine(context.ObjectToString(result));

Actual output

["\"a\"#\"b\""]

Expected output

["a#b"]

I think it happens because context.ObjectToString is called inside array.join when evaluating so both the lazy evaluation and display logic is increasing _objectToStringLevel:

Proposed solution

Pass state as parameters to ObjectToString (defaults to 0) instead of using instance variables to avoid side-effects
