Comment 4 for bug 497143

Okay, I have now made my proposed changes into a branch and linked it to this bug. I have never used launchpad to do this before, so please review with mistake-detection turned on.

To repeat this: It is certainly my opinion that this syntax (execute_view("aaa", "bbb", descending=True, group=True)) is way more elegant than passing a dictionary, but if there is any technical reason not to this, it should of course not be done.
