Re: Request for Feedback - Unsigned Right Shift Operator

CPU designers don't make their CPU's support an instruction like slau (shift left arithmetic unsigned) for simplicity of instruction set architecture. Anyway simplicity of instructions is not important for PHP. When one wants to use <<<, let them use it. -- martina.
