SliceIfD1StaticArray

Utility intended to help with situations when generic function had to return its templated argument which could turn out to be a static array. In D1 that would require slicing such argument as returning static array types is not allowed. In D2, however, static arrays are value types and such slicing is neither necessary nor memory-safe.

template SliceIfD1StaticArray (

) {

alias SliceIfD1StaticArray = T;

}

foo("abcd"); // wouldn't work if `foo` tried to return just T
