No it's not similar, 

`return *[1, 2]` means `return 1, 2`

similar would be:

`return *[1]` means `return 1`

in general, splatting in a context that takes a coma separated list of items (method args, rescue, return, next, multiple assignment) is supposed to destructure the array.  The array should be gone, only the elemnts remain, so returning the `[1]` is wrong.

*[x] should mean x as it already does for arguments
