That covers the main objection I'm aware of; that duplicated code
quickly becomes wrong.

Another objection might be that it takes "too much" time to write the
same code twice. One solution to that is to use a decent IDE (Emacs and
GPS will both copy the spec to the body the first time). Another
solution is to remember that reading is much more important than
writing.

Yes, it's in the language standard.
