This module provides some useful logging/debugging functions.

Warning

This module is not intended for general use - it is solely for development/debugging purposes. Do not use it unless you know know what you are doing.

When this module is imported, it monkey patches the CallQueue class in a devious and dangerous manner to allow for more informative debug statements. Therefore it’s a bad idea to even import this module, unless you really know what you are doing.

Warning

Just don’t import this module, ok?
