In fact, ref in general in D is a lot more rare than in languages like C++. The main reason to use it for arrays is when you need changes to the length to be visible to the caller... which is fairly rare.
In general many parameters are passed as const, the called function never changes the parameter. Which brings the question, will the compiler optimize the parameter so that the string is only passed as a pointer underneath when it knows it is a const?
