Core Utilities
==============

The core utilities provide fundamental functionality for configuration,
class manipulation, function composition, and common operations.

config
------

Configuration management with the ``Setting`` class - a nested dictionary
with dot notation access, lock/unlock mechanism, and environment-based
configuration loading.

classes
-------

Class utilities including singleton enforcement, memoization, lazy properties,
metaclass resolution, and dynamic instance extension.

.. automodule:: libb.classes

func
----

Function decorators and composition utilities: compose, decompose, repeat,
delay, suppresswarning, MultiMethod dispatch.

iter
----

Iterator utilities extending itertools: chunking, partitioning, windowing,
flattening, grouping, and sequence operations.

.. automodule:: libb.iter

phone numbers, capitalization, and custom number formats.

path
----

Path operations: add to sys.path, get module directory, context manager
for directory changes, script name extraction.

module
------

Module management: dynamic importing, module patching, class instantiation,
virtual modules, package discovery.
