Well, yea, it's debatable whether Java's String is final for a good
reason or not.
About concatenation. I just added a test for that. new Uri('...') +
'string' and 'string' + new Uri('...') both work as expected. So
assuming it is two strings being concatenated it will work anyway. You
can also use it to test a regexp: (/^...$/).test(new Uri('...'))
So I guess we're down to whether or not the String-manipulation
methods such as substr, replace etc. are needed. And that boils down
to whether or not a URI is a String?
IMO, it isn't. Same as the DOM isn't a giant HTML string. Now an e-
mail would probably be sent around as a string in it's serialized
form. But if we're going to do manipulations on it, I don't think it's
a string anymore. Same as we (usually) don't do manipulations on HTML
as strings but we do pass around serialized HTML when we don't have to
manipulate it.
