I also wasn't sure it would be useful, but in the case of fall-through, I can see how it might come in handy to pass the matched string. That will go into the next revision.

I'm not married to the name 'new' (and when I package it with other flavors of Case, it will certainly have a different name), but I didn't have a better name. I think it's just as legitimate to call a factory "new" as it is to call an OO constructor "new". The users are expected to read the documentation.

I left out a default identifier because I didn't want to have a string that might conflict with an alternative. But it occurred to me that a call to a subroutine that returns an empty list could be tucked in there and be absolutely transparent. That will also be in the next revision.

I don't know what a continue/finalise block should do here. Could you explain?

Thanks for your input.
