Yeah, it would be useful to have some use cases and examples here to
work from. E.g. I suspect we may want to have a method at some point
that considers these equal:


even though they would always be considered strictly distinct
currently (and some servers reportedly rely on this distinction).

Concrete suggestions for URLQuery are very much welcome. For behavior too.

get()/getAll() are clear.

set() not so much:

what happens? Or with set("x", [1,2])? And set("x", [1,2,3]? Idea:


So set() replaces values in order, removes parameters for which no
values are set, and adds parameters if there are no existing

I think that calls for add() as well, which simply appends a
parameter, irrespective of what is there now.

Allowing new FormData(URLQuery) makes sense to me.

Yeah, that was my thinking too.
