Hi Michael, The way you used the arrow operator in the example would be the way I expected it to work, namely by explicitly addressing the context, but it seems that it doesn't. It's actually implicitly binding the first argument of the function on the right to the value on the left. Or is there an exception I don't know about?
Thanks.

Also, of course, "!" changes the context item, so @address => replace(@postcode, "", "q") works, while @address ! replace(@postcode, "", "q") doesn't.
