Note that in my proposal I suggested to allow array deconstruction and ignoring extra elements on the right side, so mass initialization may be implemnted by something like this: const ZEROES: array [1..10] of Integer = (0, 0, ..., 0); ... (x, y, z) := Tuple(ZEROES); alternatively: function Repeat(AValue: Integer; ACount: Integer = 10): TIndegerDynArray; ... (x, y, z) := Tuple(Repeat(777)); Anyway, I do not think mass-assignment of the same value is particularly important compared to the general case of mass-assignment of arbitrary values. -- Alexander S.
