"""
|
|
This magical module will rewrite all public methods in the public interface
|
|
of the library so they can run the loop on their own if it's not already
|
|
running. This rewrite may not be desirable if the end user always uses the
|
|
methods they way they should be ran, but it's incredibly useful for quick
|
|
scripts and the runtime overhead is relatively low.
|
|
|
|
Some really common methods which are hardly used offer this ability by
|
|
default, such as ``.start()`` and ``.run_until_disconnected()`` (since
|
|
you may want to start, and then run until disconnected while using async
|
|
event handlers).
