Why are you using ref? Take that off and you can pass any array, including null, with ease.
Because dynamic arrays are passed by value to functions. Will it make another copy of array, if I'll pass array by value?
Looks like it won't (I've checked pointers), but I read in wiki (http://en.wikibooks.org/wiki/D_%28The_Programming_Language%29/d2/Strings_and_Dynamic_Arrays#Passing_Dynamic_Arrays_to_Functions) that it will copy "structure that contains the -pointer to the first element- and the length is copied and passed". Does it mean something else? maybe i don't understand it correctly.
