We have a tankless water heater, have had for about 10 years. A great device. Last night my wife went to take a shower, water wasn't heating. Error code 110e on the heater. Looked it up, not very helpful. Called for service. The chap came this morning, said it could be a couple of things, and started by cleaning the condensate filter. He called me down, and showed me the filter. There was a dead bee in the filter. He cleaned the filter, and the heater works perfectly. He debugged the water heater.

I hope I demoed a usable example of lisp's binding error handlers, which I think are a common point of confusion because it is a #lisp principle that is still just secret alien technology. I also point you to and describe finding lisp's included demos
Until eight hours from now, when https://en.wikipedia.org/wiki/Kent_Pitman demos his python port of it live.
