This doesn't work with tools, so I would be very annoyed if I had to work
with this.

An IDE friendly implementation can be found here:

Despite having written these, I've never actually used them. Such magic
would not be OK at work or in a library. But I've wanted to use them so
many times, and a method blessed by the Python language and community would
be so great.
