github.com/dlsniper/debugger (go): Debugger package allows an application to be compiled for production without incurring any penalty due to instrumentation.  When the time comes to use a debugger and inspect your code, use the -tags=debugger build tag to switch the implementation to one that will set labels that can be displayed in the debugger.  The current implementation relies on pprof labels to be created and then the debugger can read them and display them.
