Yes.  And if you are curious you can try it by yourself.  

|How about:
|[*(1..4)]
|which in 1.8.x produces [1, 2, 3, 4]

Currently,

[1..4]

This may be an issue.

|and which of these will change in 1.9?
|
|def a(*arg)
|     p arg
|end
|
|a("foo\nbar")
|which in 1.8.4 prints ["foo\nbar"]

["foo\nbar"]

|a((1..3))
| prints [1, 2, 3, 4]

[1..3]

|a(1..3)
| prints [1..3]

[1..3]

|a(1..3, "foo\nbar")
|prints [1..3, "foo\nbar"]

[1..3, "foo\nbar"]

|a(*"foo\nbar")
|prints ["foo\n", "bar"]

["foo\nbar"]

|a(*(1..4))
|prints [1, 2, 3, 4]

[1..4]

|  *a = "foo\nbar"
|  a gets  ["foo\nbar"]

["foo\nbar"]

|  *a = (1..4)
|  a gets  [1..4]

[1..4]

|  *a = "foo\nbar", (1..3)
|  a gets ["foo\nbar", 1..3]

["foo\nbar", 1..3]
