{
    new Person { Name = "Foo", Age = 99 },
    new Person { Name = "Bar", Age = 33 }
}.AsQueryable();

var config = new ParsingConfig
{
    ConvertObjectToSupportComparison = true
};

var results = persons.Where(config, "Age > 50").ToList();

Declaration

public bool ConvertObjectToSupportComparison { get; set; }
