Issue #3916 has been updated by trans (Thomas Sawyer).


@drbrain Wouldn't using priorities and setting such a warning to a very low priority solve this?

 I have a feature request: Please add a flag to the ruby command line to make warnings fatal.
 
 It would be really handy when debugging and testing to make warnings fatal.
 
 It's not always obvious what bit of code is causing the code that has the warning to execute.  Having a full exception style trace back is very handy.
 
 In addition, if you're doing tests, it would be good to have it raise an exception if a warning is fired.  See http://stackoverflow.com/questions/660737/can-you-ask-ruby-to-treat-warnings-as-errors for an example.
 
 Thanks!
