I don't, really. for is a list comprehension, and so it needs
bindings... Something to generate the list from.
Also, how is a lazy sequence of mouse events supposed to work? does it
block? What happens when there is no mouse event? does the sequence
just end? What if you happen to take the last event, and then the
sequence ends, after which another event comes in? for wouldn't know
what to do in the general case.
Anyway, I don't think it's worth the trouble; it's not especially
functional style either. If you need such a construct, I believe it
would be best to make a new function, with a more fitting name.
