Members will be mutable during the execution of __init__ but read-only afterwards.</p>

Dict is the notable exception. Regardless, here is a protocol that objects may implement that facilitates turning immutable object mutable and vice-versa.</p>

This airms to make easier to develop multi thread object-oriented programming.</p>
