Is there a convenicene function for assigning an empty dynamic

cast(int[])[];
_range = cast(D[])[];
If the variable is already typed, you can use [] otherwise you
can use cast(T)[] or (T[]).init to avoid casts.

Ok. Enough for now...but Is there a way to avoid this array
special handling:
static if (isArray!R)
_range = (D[]).init;
else
_range = R(); // return empty range
through some initializer expression for _range that covers both
R()
and
(D[]).init
?
