  Implemented to define a dynamic query builder function for an operator, that is

  a module that implements `Permit.Operators.GenOperator`.



  For example, when an operator is defined in the `Permit.Operators.Eq` module, its

  dynamic query builder function should be defined in `Permit.Operators.Eq.DynamicQuery`.



  Part of the private API, subject to changes and not to be used on the application level.
