Feature #21454: "undefined method 'break' for an instance of Binding"

Running my code with rdbg and using binding.break, it is a bit unfortunate that subsequently running the code without rdbg, it fails with error such as:

     NoMethodError:
       undefined method 'break' for an instance of Binding

Could this method become no-op if the rdbg is not loaded? If there was some concern about this, then it could print some helpful warning or what not.

Use no-dbg.rb with RUBYOPT=-rno-dbg when you run without rdbg.

class Binding
  def break = nil
end

In today's dev meeting, we emphasized that it's important to ensure binding.break (or debugger) is removed before release, so having it as a no-op is a bad idea.

BTW debug.gem supports specifying breakpoints by adding environment variables for example, and you can ignore them without rdbg.
However, specifying the file and line number is difficult, so I think good editor support would improve the situation.

Interesting idea. Assuming that I should request this feature in rdbg project.

Sorry, could you please elaborate? Maybe share some example?
