This function was using a confusing syntax because `Isolation.IsDefault()`
and `Isolation.IsHyperV()` don't accept an argument. It's valid (see below),
but just confusing, so let's use a more common approach.

```go
package main

import "fmt"

type NameSayer string

func (f NameSayer) SayMyName() {
	fmt.Println(f)
}

func main() {
	var foo NameSayer = "my name is"
	foo.SayMyName()

	NameSayer("my name is..").SayMyName()

	// Thought SayMyName() would take no arguments? Think again!
	NameSayer.SayMyName("slim shady!")
}
```

While at it, also renamed the `container` argument as it was shadowing
the `container` import.
