#### 19.2.2.7 NIL as a Component Value

As a pathname component value, nil represents that the component is “unfilled”; see Merging Pathnames.

The value of any pathname component can be nil.

When constructing a pathname, nil in the host component might mean a default host rather than an actual nil in some implementations.
