Null module:
Responds to all actions and requests for members with a null object.

For example, this code will execute the debugging tools in development, but
won't do anything in production.

if environment == development:
    import ExpensiveDebugging
else:
    import null as ExpensiveDebugging

dev_tool = ExpensiveDebugging.tool()
with dev_tool(code) as d:
    for line in d:
