Catch errors during callbacks

[kLabz]

Allows continuing and calling later callbacks (with an error state).
Not 100% sure it is the behavior we want, but I did need that when working with save callbacks

Intuitively I'd say that IF we want to do that, the catch should be around the inner f() call. Having it around a given set of callbacks seems a bit random.

Do you mean List.iter (fun f -> try f() with Error.Error err -> handle_error err) (List.rev l); ?

[Simn]

Yes
