// LET'S USE THE TRAUMA THERAPY INTELLECT APPROACH.
// The core is that we focus our energy on handling our failures.
// This can involve taking the time to understand them, or entering a trauma state and asking the user for help.
// 	Trauma state must be logged.  Solution must be stored.  Can just be creation of a trauma-handling pattern, I suppose.
// 	Understanding will likely involve breaking behavior into steps
// 		maybe then backtracking from a failure to the steps that caused it, and opening those steps up into substeps

// GDB HAS A MACHINE INTERFACE MODE THAT COULD BE USED TO MANAGE EXECUTION WITH LEARNING

// DYLOAD NOTES:
//
// 	#define _GNU_SOURCE
// 	#include <dlfcn.h>
// 	// LM_ID_NEWLM makes a new isolated namespace
// 	void *handle = dlmopen(LM_ID_NEWLM, "./path.so", RTLD_NOW); // NULL -> failure
// 		link with -ldl
// 		links .so with -shared -fPIC
// 	void *addr = dlsym(handle, "symbolname"); // NULL -> failure
// 	int res = dlclose(handle); // 0 -> success (dlerror)
//
//	extern "C" // place before exports to demangle their symbols
//
// 	__attribute__((constructor)) and __attribute__((destructor)) functions
// 		are called on load/unload
// 		alternatively use _init() and _fini_() and pass -nostartfiles to gcc
// 		atexit() is preferred

// problem: how does a .cpp file reference another file with a number
// answer: use #includes or interpret the whole shebang as numbers

// please provide for handling a parameter next.
//
//      concept: dynamic values aquirable from inside code, i.e. what-number-called-me what-number-comes-after-me
//      thinking the code would likely evolve to handle some inputs differently
