Description
Not quite reduced test case, but the problem is 
is ending up as [2] versus [[2]] (where 2 may not be 2 depending on which test case you are looking at below). Interestingly Ruby 1.9 behaves the same as us so it is debatable whether we need to fix this at all:
class X
def to_ary
[1, 2, 3]
end
end
x = X.new
puts "a, (*b) = 1, [2]"
a, (*b) = 1, [2]
p a == 1
p b == [[2]]
p b
puts "a, (*b) = 1, [x]"
a, (*b) = 1, [x]
p a == 1
p b == [[x]]
puts "a, (*b) = 1, [*x]"
a, (*b) = 1, [*x]
p a == 1
p b == [[1, 2, 3]]
puts "a, (*b) = 1, [*2]"
a, (*b) = 1, [*2]
p a == 1
p b == [[2]]
As Charlie suggested and it is a reasonable suggestion....These seem like bugs in 1.8.7 since the double array really does not seem like it is what you want?
