Would it make more sense for CancellationException to not be an Exception? It really doesn't fall under that category. It doesn't represent some kind of issue; it represents that we don't care about the result anymore. It seems like it should inherit from Throwable and be treated entirely differently.

Issue is that it maps to Java's equivalent, so we're kinda constrained on what it can be

A lot of things are exceptions though, including some very fatal ones that should not be caught

[CLOVIS]

@Youssef Shoaib [MOD] To be pedantic, they are not exceptions, they are throwables, which can represent non-exceptional weird things

InterruptedException is though, and it's very analogous to CancellationException

[CLOVIS]

IMO, based on the initial definitions of Throwable/Exception, InterruptedException shouldn't be an Exception either

[CLOVIS]

Looks like it's an exception because the Java authors wanted it to be checked

[CLOVIS]

so it's two levels of "it's like that because of old stuff"

[Youssef Shoaib [MOD]]

That's very fair yeah. Issue is though that we really want to support Java's cancellation exception in the same way. It's also never good practice to catch Exception anyway
