Hi,

If I understand correctly it is possible in this proposal to use normal a=
rguments after using an unpackable argument:

	=24arr4 =3D array(...=24arr1, ...=24arr2, 111); //valid

This is something that is not possible when using argument unpacking in f=
unction calls:

	=24result =3D=C2=A0some=46unction(...=24arr1, ...=24arr2, 111); //invali=
d

While I personally like the more permissive variety in this R=46C, I thin=
k this could be a confusing inconsistency, and for clarity's sake it woul=
d be better to keep both instances of the unpacking syntax as consistent =
with each other as possible.

Best,
Stijn=C2=A0

received.
