Thanks all, and thanks Nathan for your detailed explanation.
Now I know the list got flattened before passing into subroutine.

First: @_[0] is legit, in that it is a 1 element slice of the array

When an array is passed as a parameter to a subroutine in perl, it is
unrolled. In other words, each element of the array is passed as a
single parameter. In order
