From (1) a compiler can infer that the type argument for <code>S</code> is <code>Slice</code>.
Similarly, because the underlying type of <code>Slice</code> is <code>[]int</code>
and <code>[]int</code> must match <code>[]E</code> of the constraint,
a compiler can infer that <code>E</code> must be <code>int</code>.
Thus, for these two equations, type inference infers
