Ruby

Hello, errors with cause are an important and very useful feature for debugging. It seems though default reporting is not showing the cause and nested causes to user. Here's a test file:

raise "GAHGAH" rescue raise "error with cause" rescue e=$! puts "Error: #{e}" puts "Cause: #{e.cause}" raise e 

As you can see, the cause of the error is not printed in any way to the console when error is raised:

$ ruby /tmp/test.rb Error: error with cause Cause: GAHGAH /tmp/test.rb:1:in `rescue in <main>': error with cause (RuntimeError)	from /tmp/test.rb:1:in `<main>
