Some other languages have the ability to add names to anonymous
functions (yes, a contradiction in terms) to aid debugging and the like.
We could also extend our `lambda' with an optional name -- it seems like
that could be generally useful beyond this particular use case -- and
then this new add-hook function could refuse to accept name-less
lambdas...
