Instead, I handle errors with try blocks and testing for undefined values; the only thing I use CATCH blocks for is to log errors differently. I don't seem to be alone in this habit – looking at the CATCH blocks in the Raku docs, pretty much none of them handle the error in any sense beyond printing a message. (The …
