+/// Construct a [`PathBuf`] from individual [`Path`] components.
+///
+/// This is a simple and legible way to construct `PathBuf`s that use the system's native path
+/// separator character. (It's ugly to see paths mixing `\` and `/`.)
+///
+/// # Examples
+///
+/// ```rust
+/// # use std::path::Path;
+/// # use vendor_webgpu_cts::path::join_path;
+/// assert_eq!(&*join_path(["foo", "bar", "baz"]), Path::new("foo/bar/baz"));
+/// ```
