+// 1. No leading slash in paths,

+//
+// 2. Backslashes are not replaced with slashes,
+//    so `http:\\example.org\` is treated like a relative path
+//
+// 3. Trailing colon is treated like a part of the path,
+//    i.e. in `http://example.org:foo` pathname is `:foo`
+//
+// 4. Nothing is URL-encoded in the resulting object,
+//    (in joyent/node some chars in auth and paths are encoded)
+//
+// 5. `url.parse()` does not have `parseQueryString` argument
+//
+// 6. Removed extraneous result properties: `host`, `path`, `query`, etc.,
+//    which can be constructed using other parts of the url.
