I’ve been a fan of link-time optimization for several years. I’ve been a fan of efficient programming for even longer. I was an early fan of C++ because features like function overloading made it easier to move decisions done at run-time in C to compile-time with C++. As C++ has become more complex over the decades, I’ve become less of a C++ fan, and appreciate the simplicity of C.
For small embedded systems like 8-bit AVRs and ARM M0, run-time error checking with assert() has minimal usefulness compared to UNIX, where a a core dump will help pinpoint the error location and the state of the program at the time of the error. Even if the usability problems were solved, real-time embedded systems may not be able to afford the performance costs of run-time error checking.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
