Are pattern guards obsolete?

Of course, this is not really the joy of
pattern guards. It is the joy of monads,
with perhaps a few character strokes
saved by a confusing overloading of (<-).

But some people do seem to be used to this
notation by now. So perhaps a good compromise
would be to use a different operator for pattern
guards, e.g. (<<-), instead of (<-).

What do you say?
