Is the rescue clause being called on descendent redefinition?

Question

Didn't find the answer on this doc, is the rescue clause called when redefining a feature?

Class A

class A

feature -- 

    process
        do
            do_stuff
        rescue
            on_fail
        end
end -- class

Class B

class B

inherit
    A
        redefine
            process
        end

feature -- 

    process
        do
            do_other_stuff -- do I have to call the rescue too?
        end
end -- class

@zx8754, why removing the language into title? – Pipo Aug 28 '19 at 15:02 — Pipo, Aug 28 '19 at 15:02
Language is in the tags, no need in the title. – zx8754 Aug 28 '19 at 15:02 — zx8754, Aug 28 '19 at 15:02

Rescue clauses are not inherited like contracts and should be supplied with every new feature body if needed.

For example the rescue in class A could use local variables which are not declared in class B. – Eric Bezault Aug 30 '19 at 07:21
So `rescue` clauses are parts of the implementation, and not part of the contract. – U. Windl May 24 '21 at 17:14
@U.Windl Right, `rescue` clauses are part of the implementation. – Alexander Kogtenkov May 24 '21 at 20:01
