Re^4: "Good" style for splicing arrays

[LanX]

Good point, Massa! I agree that grepping for defined is no general fix of the problem!

But in cases you really need to get undefs, the listflattening approach is better.

e.g. parameter passing  ($self,$x,$y,@opt)=@_;

so the two approaches are actually not two ways to do the same thing, but two different thing which only seemed interchangebal.
