Subject: Change in semantics on multiple values

I noticed this here: http://www.rubygarden.org/ruby?Rite

    a, b, c = x
    # where x = [1,2,3]
    # should they be:
    # a=1,b=2,c=3
    # or:
    # a=[1,2,3],b=nil, c=nil

Matz still hasn't decided, but it will be either: 

Represent multiple values by subclass of Array, say Array::Values<Array 
  or 
Separating arrays and multiple values strictly in syntax

What about the syntax:

a, b, c = *x
# a=1,b=2,c=3
a, b, c = x
# a=[1,2,3],b=nil,c=nil

or

a, b, c = *x
# a=1,b=2,c=3
a, b, c = x
# Raises an argument count mismatch type exception

They are what would make sense to me.
