Hard to decide use-cases without much discussion about how it works. It converts 2 hours to seconds but not 2 pb to gb. Does this use frink under the hood? If not.. maybe it should. An AI front-end that's fine-tuned to quietly "compile" to frink on the backend feels sorely needed.

My next go-to test for this kind of thing would be converting bananas to petabytes, hoping the backend is smart enough to try and use the bekenstein bound. Wolfram (still) fails this kind of test at the moment.

can I refer to a previous result in a new expression?
