Details about the `async def` syntax for *path operation functions* and some background about asynchronous code, concurrency, and parallelism.

## In a hurry?

<abbr title="too long; didn't read"><strong>TL;DR:</strong></abbr>

If you are using third party libraries that tell you to call them with `await`, like:

```Python
results = await some_library()
```

Then, declare your *path operation functions* with `async def` like:

pkg html/template, type Srcset string
pkg math, func Erfcinv(float64) float64
pkg math, func Erfinv(float64) float64
pkg math, func Round(float64) float64
pkg math, func RoundToEven(float64) float64
pkg math/big, const MaxBase = 62
pkg math/big, method (*Float) Sqrt(*Float) *Float
pkg math/big, method (*Int) CmpAbs(*Int) int
pkg math/rand, func Shuffle(int, func(int, int))
pkg math/rand, method (*Rand) Shuffle(int, func(int, int))

pkg math/big, const MaxPrec ideal-int
pkg math/big, const MinExp = -2147483648
pkg math/big, const MinExp ideal-int
pkg math/big, const ToNearestAway = 1
pkg math/big, const ToNearestAway RoundingMode
pkg math/big, const ToNearestEven = 0
pkg math/big, const ToNearestEven RoundingMode
pkg math/big, const ToNegativeInf = 4
pkg math/big, const ToNegativeInf RoundingMode
pkg math/big, const ToPositiveInf = 5

	err := storage.AppendFile(context.Background(), "foo", "path/to/myobject", []byte("foo"))
	if err != nil {
		t.Fatalf("unexpected error %v", err)
	}

	testCases := []struct {
		volumeName     string
		prefix         string
		expectedResult []string
		expectErr      bool
	}{
		{"foo", "path", []string{"to/"}, false},
		// prefix not found error.
		{"foo", "nodir", nil, true},
	}
