           Summary: Feature Request: version(D_DebugInfo)
           Product: D
           Version: D2
          Hardware: All
                OS: All

Hello. I'd like to have:

    version (D_DebugInfo)
    {}
    else
    {
        version = enableFeatureThatIsAnnoyingWhenDebugging;
    }

Is there a way to know if debug info is being emitted when compiling?
"debug" is not cutting it because sometimes you really need to debug with or
without -debug, and with or without -O.
I would want -g.
