-Debug backtrace functions are a very useful debug tool. However, for big projects, the problem that often happens is that when something happens inside the code, the debug trace becomes so big it's unmanageable. This is because it includes the arguments, and those can be complex data arrays, huge objects, etc. so when the trace is prepared or printed out, the useful information is drowned in the mass of white noise.+Debug backtrace functions are a very useful debug tool.

 The default options will be DEBUG_BACKTRACE_PROVIDE_OBJECT, which agrees with current functionality for both functions. The default options will be DEBUG_BACKTRACE_PROVIDE_OBJECT, which agrees with current functionality for both functions.
