Really?  I didn't figure out what the code illustrates, but my recent
attempts to use Lambda have been a dismal failure, mostly because of
subtle (and sometimes not-so-subtle) differences with Bind.  For
example, Lambda doesn't seem to support get_pointer to dereference
through smart pointers.  The tuple/reference issue I posted about
yesterday was another obstacle.

I'm rather discouraged with how difficult it is to use standard
algorithms -- or even algorithms over sequences as opposed to
iterators -- to write something that could be coded quickly using dumb
loops.  I hold out some hope that the long-promised integration of
Lambda and Phoenix will help to solve these problems, but it's hard
to tell when (or if) that's actually coming.
