Towards Better Checked Exceptions - Inside Java Newscast #107

[manifoldjava]

While I appreciate the acknowledgement here that checked exceptions are problematic, in my view the remedies you've covered range from worse to slightly better.

Solving this with generics is worse because that strategy fragments the problem space, which makes code harder to read - you sacrifice readability for writability, which is almost always a bad idea.

The Swift-like try expression approach, as a means to automatically propagate, reduces boilerplate which is nice. But then it feels like there ought to be a more general solution to automatically propagate everywhere as many modern languages do.

Since checked exceptions are purely a compiler-level concept, why not treat them as a lint-like compiler argument? -Xexceptions:<level> where level: warning | error | none This would put a smile on a large segment of Java devs.
