> 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.
some examples
`method_call *[a]` is `method_call a` as expected
`rescue *[a]` is `rescue a` as expected
`[*[a]]` is `[a]` as expected
`b = *[a]` is `b = [a]` why?
`(next|return) *[a]` is `(next|return) [a]` why?
the intuitive, expected and logical behavior would be for `*array` to consistently destructure, when used in a coma separated list context
----------------------------------------
Bug #10837: spatting a single element array produces an array instead of a single value for return and next

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