It makes it less likely to make mistakes, doesn't it?  E.g. in cases
where you pass an argument by value where you really meant to pass it by
reference.  I think our code would benefit from doing this consistently,
not only because it tells the compiler which classes it makes sense to
copy and which ones don't, but also because it makes the semantics of
the class clearer to developers.
