I agree with the above remarks, but note that if taken
literally the QED system would have to cope with remarks like
"similarly", "proof trivial", "by symmetry", etc. Ultimately, it
might be possible to cope with some proof descriptions containing
such remarks by building tactics that can try to reproduce the
proofs they imply. However, it will certainly be a non-trivial
task.
