Sets and dict keys are not recursively frozen because they do not contain mutable data by convention. The main exception to this rule is that dict keys and set elements are often instances of mutable objects that support hash-by-id, which this function can't convert anyway. >>> freeze(set([1, 2])) pset([1, 2]) >>> freeze([1, {'a': 3}]) pvector([1, pmap({'a': 3})]) >>> freeze((1, [])) (1, pvector([])) c s s | ]\}}|t |�fV qd S )N)�freeze)�.0�k�v� r �F/opt/alt/python37/lib64/python3.7/site-packages/pyrsistent/_helpers.py� <genexpr> s zfreeze.<locals>.<genexpr>) �type�dictr �six� iteritems�listr �mapr �tuple�setr )�o�typr r r r s r c C sh t | t�rttt| ��S t | t�r8tdd� | �� D ��S t | t�rJt | �S t | �t krdt tt| ��S | S )a� Recursively convert pyrsistent containers into simple Python containers. - pvector is converted to list, recursively - pmap is converted to dict, recursively on values (but not keys) - pset is converted to set, but not recursively - tuple is converted to tuple, recursively. >>> from pyrsistent import s, m, v >>> thaw(s(1, 2)) set([1, 2]) >>> thaw(v(1, m(a=3))) [1, {'a': 3}] >>> thaw((1, v())) (1, []) c s s | ]\}}|t |�fV qd S )N)�thaw)r r r r r r r > s zthaw.<locals>.<genexpr>) � isinstancer r r r r r r r r r r )r r r r r * s r c s t � �� fdd��}|S )a Convenience decorator to isolate mutation to within the decorated function (with respect to the input arguments).
