The Phobos function staticArray can be used to infer the array length 
while explicitly specifying (or inferring) the element type:

     import std.array : staticArray;
     auto a = [1, 2, 3, 4, 5].staticArray;  // inferred int[5]
     auto b = [1, 2, 3, 4, 5].staticArray!float;  // inferred float[5]
