Feature #9918: Exception#cause should be shown in output and #inspect

• Status: Open

[Eregon (Benoit Daloze)]

Exception#cause has been added in Feature #8257.
But the cause is never shown, one needs to inspect exc.cause to know the cause.

The cause should be shown by default, for instance:

begin
  raise "cause"
rescue
  raise "wrapper"
end

Should output:

-:4:in `rescue in <main>': wrapper (RuntimeError)
       from -:1:in `<main>'
Caused by:
-e:1:in `<main>': org (RuntimeError)

And not only the first 2 lines.
Logically, #inspect should also include the cause such as:

#<RuntimeError: wrapper cause:#<RuntimeError: org>>

What do you think?
