var s []string
_ = min(s...)               // invalid: slice arguments are not permitted

<p>
For numeric arguments, assuming all NaNs are equal, <code>min</code> and <code>max</code> are
commutative and associative:

<pre>
min(x, y)    == min(y, x)
min(x, y, z) == min(min(x, y), z) == min(x, min(y, z))

...all these parameters are required because the default value is `...` (Ellipsis).
