Thank you very much. That sounds much better than just a bare "eval".

I could probably also get pickle to do the job, also. A brief inspection 
suggests it puts repr(dict) in some simple boilerplate (at least for 
trivial dicts such as mine -- consisting only of strings and numbers). 
But I'd sure have to learn more before I'd believe that. Your safe eval 
seems much safer from that angle.
