Functions, including filters, tests, and finalize, all use pass_context, pass_eval_context, and pass_environment. A single variable, jinja_pass_arg is set to an enum member. The enum class has a from_obj method to check if a given function/callable class has the variable. It also handles showing deprecation warnings for all the other names.
