Don't do this without `dup`ing. Quoting the documentation:
Oh, whoops. I thought those special variadic args were always allocated

Nope,
Which makes it annoying, what if the argument IS passed on the heap?
Fortunately, there is a solution (one I use in dcollections):
foo(T[] x...)
foo(T[] x)
Can be overloaded. If you ever pass in parameters one at a time, the
first is called, and x is guaranteed to be on the stack.
The second is called with an actual array only, you are able to not
'dup', and just warn people that x will NOT be dup'd in that case.
