 A `qenv` inherits from the `environment` class, behaves like an environment, and has the following characteristics:
 
--	The environment is locked, and data modification is only possible through the `eval_code()` and `within()` functions.
-- It stores metadata about the code used to create the data.
-- Is immutable which means that each code evaluation does not modify the original `qenv` object directly.
