This library provides a simple immutable list class for Python.

- drop-in replacement for `list`
- hashable (if list contents are hashable)

Installation
------------

Install the `frozenlist2` package from PyPI.

```
pip install frozenlist2
```

Usage Example
-------------


```python
from frozenlist2 import frozenlist

# Make a list
elems = frozenlist([1, 2, 4, 8])

# Attempt to modify it
elems.append(16)  # Will raise exception!
```
