@mfilenko hope you've been well these past couple years since you've opened the PR and apologies for so poorly maintaining this package.

I think this is a good idea but would like to split things up a bit. I'm thinking of extracting the name cleaning into something like a separate clean_name method. That would make the normal lookup method work for some of the situations you test for here.

I'd likely rename the deep_lookup flag to something else more descriptive, but I can't think of anything just yet. startswith() is a good method but I'm wondering if there are other methods people might want to use here. Passing a fallback_func or something could allow someone to use their own fallback lookup method.

It's been a very long time since you opened this so I wouldn't ask you to make these changes. If you're good with this approach I'll close this PR, make the changes, and give you credit in README for the change.
