It's unfortunate that elisp has two incompatible variants, throw/catch and 
signal/condition-case, of essentially the same control structure. In practice 
throw/catch tends to be used more for non-error situations, but that's just a 
matter of style -- the underlying mechanisms are basically the same.

In any case the patch apparently wasn't bad enough to be rejected outright so 
it's boldly been pushed to master. If the general opinion is that :no-error (or 
something else) would be a better name than :success, I'll make the change in a 
blink.

I didn't do any serious search for places where the new construct would be 
profitably employed but there are bound to be a few. Have a look at 
`load-completions-from-file`, for example.
