frozenlist¶
A list-like structure which implements
collections.abc.MutableSequence
.
The list is mutable until FrozenList.freeze()
is called,
after which list modifications raise RuntimeError
. A
FrozenList
instance is hashable, but only when frozen.
Attempts to hash a non-frozen instance will result in a
RuntimeError
exception.
