maybe add a switch for this decorator will be better.
We develop a project has two model: development environment and production environment，generally speaking，we want to this decorator works for dev environment, not production environment. if add a switch, we can close this decorator in production environment and not comment the decorator.

like this:
`
def snoop(output=None, variables=(), depth=1, prefix='', switch=True):
write = get_write_function(output)
@decorator.decorator
def decorate(function, *args, **kwargs):
target_code_object = function.code
if switch:
with Tracer(target_code_object=target_code_object,
write=write, variables=variables,
depth=depth, prefix=prefix):
return function(*args, **kwargs)
else:
return function(*args, **kwargs)

return decorate`

I'm against that. Changing to switch=False is about as easy as commenting out or removing the decorator, and the latter is much clearer. This is a tool for debugging, not meant to be checked into Git or used in production.

I need remove the decorotor befor deploy my project to production environment if I use this decorator for debugging, this process need to modify code(maybe just remove the decorator), maybe It will bring out unpredictable errors or exceptions.

It's normal that you'd remove the decorator before deploying to production.
