    def call(mocks) do
      a = [1, 2, 3] |> List.first() |> Mok.inject(mocks, "unmatched") # 1 (not injected)
      b = [1, 2, 3] |> List.first() |> Mok.inject(mocks, "matched") # 10 (injected)
      c = [1, 2, 3] |> List.first() |> Mok.inject(mocks, nil) # 1 (not injected)
      d = [1, 2, 3] |> List.first() |> Mok.inject(mocks) # 100 (injected)

      a + b + c + d
    end
  end
```

```elixir
require Mok

assert 4 == Target.call(%{})

assert 112 ==
          Target.call(
            Mok.mock(%{
              {&List.first/1, "matched"} => 10,
              &List.first/1 => 100
            })
